Обсуждение: pgsql: Tweak configure to attempt to add -qnoansialias to CFLAGS

Log Message:
-----------
Tweak configure to attempt to add -qnoansialias to CFLAGS whenever running
on AIX with a non-gcc compiler.  The previous coding would do this only if
CC was exactly "xlc"; which is a bad idea, as demonstrated by trouble report
from Mihai Criveti.
