Subject: Split the LDFLAGS make variable into two parts: LDFLAGS is now used
 for 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.
