AIX: Test the -qlonglong option before use.
xlc provides "long long" unconditionally at C99-compatible language levels, and this option provokes a warning. The warning interferes with "configure" tests that fail in response to any warning. Notably, before commit 85a2a8903f7e9151793308d0638621003aded5ae, it interfered with the test for -qnoansialias. Back-patch to 9.0 (all supported versions).
