Hi!

AIX with -fPIC emits especially for __attribute__((constructor)) functions
symbol names with random seed in it, which breaks bootstrap comparison.
libstdc++ uses -frandom-seed=$@ everywhere, libgomp on HPUX uses
-frandom-seed=fixed-string (should be eventually changed to $@), this patch
adds it for AIX too.

Bootstrapped/regtested on x86_64-linux, i686-linux and
powerpc-ibm-aix7.2.0.0, committed to trunk and 7.1.

2017-04-27  Jakub Jelinek  <jakub@redhat.com>

	PR bootstrap/80531
	* configure.tgt (*-*-aix*): Add -frandom-seed=$@ to XCFLAGS to avoid
	bootstrap compare failures.
