AIX: Test the -qlonglong option before use.
xlc provides "long long" unconditionally at C99-compatible languagelevels, and this option provokes a warning. The warning interferes with"configure" tests that fail in response to any warning. Notably, beforecommit85a2a89, it interfered with thetest for -qnoansialias. Back-patch to 9.0 (all supported versions).
