Adding a workaround to gcc to enforce -O2

Hello!

We have a number of important packages failing to build from source on ia64
because they are using the -O3 optimization level which is currently broken
for this target in gcc [1].

Since I don't know when the upstream bug will be fixed, I would suggest patching
gcc on ia64 such that -O3 is always mapped to -O2 and therefore the broken -O3
optimization level is never used.

Any other opinions?

Adrian
