Remove stale Autoconf checks for Perl

Subversion r110220 (Git commit 03b8fe495d716c004f5491eb2347537f115ab2d8) for
PR25884 "libgomp should not require perl to compile" removed all '$(PERL)'
usage from libgomp -- but didn't remove the then-unused Autoconf Perl check
itself.  Later, this Autoconf Perl check appears to have been copied from
libgomp into other GCC libraries, likewise unused.
