Summary: Linux -ffast-math CFLAGS break i386 floating point

Initial Comment:
This issue has been reported on numerous Linux distributions:

https://bugzilla.gnome.org/show_bug.cgi?id=611936
https://launchpad.net/bugs/673307
https://bugzilla.redhat.com/show_bug.cgi?id=629964

The fast-math optimization produces broken test results on libdbi-drivers sqlite3 test suite (it "passes" but clearly fails to process the floating point number properly) on i386. The fast-math option should therefore be dropped. Also, arch-specific optimizations should probably be removed in favor of allowing the user to choose their optimizations with CFLAGS.

Message:
I've removed all platform-specific optimizations and made sure that
user-supplied CFLAGS settings are picked up correctly. Please check the
latest CVS revision to see if it fixes your problem.
