Optimizer crash code with pentium4 arch.

[ydario]

Building python 2.7 with -O3 -march=pentium4 crashes the build after creating PYEXPAT.
-O3 for plain i386 is fine.
-O2 -march=pentium4 is fine too.

Also similar issues are present when building AOO connectivity and dbaccess code. In this case, -O0 is required to get working binaries.

Just for the record:
also with GCC 446 -O3 doesn't always work. We had to add also some -O1
to InJoy
