This way we don't need RANLIB anymore, making it a bit simpler for the meson
build to generate Makefile.global for PGXS compatibility.
FreeBSD, NetBSD, OpenBSD, the only platforms where we didn't use AROPT=crs,
all have supported the 's' option for a long time.
On macOS we ran ranlib after installing a static library. This was added a
long time ago, in 58ad65ec2def. I cannot reproduce an issue in more recent
macOS versions. This is removed now.
Based on discussion with Tom, I left the 'touch' at the end of static
libraries generation, added in 826eff57c4c, in place. While it looks like
current versions of Apple's ar/ranlib don't need it, it was needed not too
long ago.

macOS has traditionally used extension .dylib for shared libraries
(used at build time) and .so for dynamically loaded modules (used by
dlopen()). This complicates the build system a bit. Also, Meson uses
.dylib for both, so it would be worth unifying this in order to be
able to get equal build output.
There doesn't appear to be any reason to use any particular extension
for dlopened modules, since dlopen() will accept anything and
PostgreSQL is well-factored to be able to deal with any extension.
Other software packages that I have handy appear to be about 50/50
split on which extension they use for their plugins. So it seems
possible to change this safely.

Move DLSUFFIX from makefiles into header files for all platforms.
Move the DLSUFFIX assignment from src/makefiles/ to src/templates/,
have configure read it, and then substitute it into Makefile.global
and pg_config.h. This avoids the need for all makefile rules that
need it to locally set CPPFLAGS. It also resolves an inconsistent
setup between the two Windows build systems.

Rather than define ld_library_path_ver with a big nested $(if), just
put the overriding values in the makefiles for the relevant ports.
Also add a variable for port makefiles to append their own stuff to
with_temp_install, and use it to set LD_LIBRARY_PATH_RPATH=1 on
FreeBSD which is needed to make LD_LIBRARY_PATH override DT_RPATH
if DT_RUNPATH is not set (which seems to depend in unpredictable ways
on the choice of compiler, at least on my system).
Backpatch for the benefit of anyone doing regression tests on FreeBSD.
(For other platforms there should be no functional change.)

It's important for link commands to list *.o input files before -l
switches for libraries, as library code may not get pulled into the link
unless referenced by an earlier command-line entry. This is certainly
necessary for static libraries (.a style). Apparently on some platforms
it is also necessary for shared libraries, as reported by Donald Dong.
We often put -l switches for within-tree libraries into LDFLAGS, meaning
that link commands that list *.o files after LDFLAGS are hazardous.
Most of our link commands got this right, but a few did not. In
particular, places that relied on gmake's default implicit link rule
failed, because that puts LDFLAGS first. Fix that by overriding the
built-in rule with our own. The implicit link rules in
src/makefiles/Makefile.* for single-.o-file shared libraries mostly
got this wrong too, so fix them. I also changed the link rules for the
backend and a couple of other places for consistency, even though they
are not (currently) at risk because they aren't adding any -l switches
to LDFLAGS.
Arguably, the real problem here is that we're abusing LDFLAGS by
putting -l switches in it and we should stop doing that. But changing
that would be quite invasive, so I'm not eager to do so.
Perhaps this is a candidate for back-patching, but so far it seems
that problems can only be exhibited in test code we don't normally
build, and at least some of the problems are new in HEAD anyway.
So I'll refrain for now.

supposing that they should set SHLIB_LINK rather than LDFLAGS_SL. Since these
don't go through Makefile.shlib that was a no-op on most platforms. Also
regularize the few platform-specific Makefiles that did pay attention to
SHLIB_LINK: it seems that the real value of that is to pull in BE_DLLLIBS,
so do that instead. Per buildfarm failures on cygwin.

linking both executables and shared libraries, and we add on LDFLAGS_EX when
linking executables or LDFLAGS_SL when linking shared libraries. This
provides a significantly cleaner way of dealing with link-time switches than
the former behavior. Also, make sure that the various platform-specific
%.so: %.o rules incorporate LDFLAGS and LDFLAGS_SL; most of them missed that
before. (I did not add these variables for the platforms that invoke $(LD)
directly, however. It's not clear if we can do that safely, since for the
most part we assume these variables use CC command-line syntax.)
Per gripe from Aaron Swenson and subsequent investigation.

another section if required by the platform (instead of the old way of
building them in section "l" and always transforming them to the
platform-specific section).
This speeds up the installation on common platforms, and it avoids some
funny business with the man page tools and build process.

mentioning all the libraries they depend on; the Darwin and AIX ports
are known to require this, and it doesn't seem to hurt any other supported
platforms. (Hence, remove code in pl/tcl makefile that tried to avoid
mentioning other libs if not needed.)

it wasn't entirely appropriate.

Bruce Hartzler <bruceh@mail.utexas.edu>. It contains shared library
support, regression test map, and the usual template files. The dynamic
loader is missing, the spin lock code apparently doesn't assemble due to
syntax problems, and semaphores are to be hoped for from Apple.
