Remove long-dead support for platforms without sig_atomic_t.
C89 requires <signal.h> to define sig_atomic_t, and there is no evidence
in the buildfarm that any supported platforms don't comply. Remove the
configure test to stop wasting build cycles on a purely historical issue.
(Once upon a time, we cared about supporting C89-compliant compilers on
machines with pre-C89 system headers, but that use-case has been dead for
quite a few years.)
I have some other fixes planned in this area, but let's start with this
to see if the buildfarm produces any surprising results.
