x86: Warn -pg without -mfentry only on glibc targets

Since only glibc targets support -mfentry, warn -pg without -mfentry only
on glibc targets.

gcc/

	PR target/120881
	PR testsuite/121078
	* config/i386/i386-options.cc (ix86_option_override_internal):
	Warn -pg without -mfentry only on glibc targets.

gcc/testsuite/

	PR target/120881
	PR testsuite/121078
	* gcc.dg/20021014-1.c (dg-additional-options): Add -mfentry
	-fno-pic only on gnu/x86 targets.
	* gcc.dg/aru-2.c (dg-additional-options): Likewise.
	* gcc.dg/nest.c (dg-additional-options): Likewise.
	* gcc.dg/pr32450.c (dg-additional-options): Likewise.
	* gcc.dg/pr43643.c (dg-additional-options): Likewise.
	* gcc.target/i386/pr104447.c (dg-additional-options): Likewise.
	* gcc.target/i386/pr113122-3.c(dg-additional-options): Likewise.
	* gcc.target/i386/pr119386-1.c (dg-additional-options): Add
	-mfentry only on gnu targets.
	* gcc.target/i386/pr119386-2.c (dg-additional-options): Likewise.
