[ooo-build] gcc4.4: extensions broken when compiled with default -O2 optimizations

[Andreas Radke]

1) Patch applied and pkg built well to vanilla m11 OOo 3.1.0 but didn't
solve our extension issue.

2) exporting ARCH_FLAGS="$CFLAGS -fno-strict-aliasing" without applying
the patch breaks the build:

3) vanilla DEV300_m50 - patch needs major rework. Fails at several places.


Any suggestions for our extension issue?
