Hi Eric,
are there any reasons (bugs) to avoid using -O2 for ROMCC?

Build-tested and tested on hardware using an ASUS P2B-F, I didn't notice any problems. However, if there are any non-obvious reasons to _not_ enable optimizations in romcc, please let me know.
Use -O2 and -mcpu=p2 as romcc options for all Intel 440BX boards.
This should hopefully make the "too few registers" error pop up less often.

I'd prefer to switch all these boards to CAR, but as this patch improves the current situation, it is Acked-by: Carl-Daniel Hailfinger c-d.hailfinger.devel.2006@gmx.net pending an answer from Eric.
I want to say to my knowledge all of the failures in romcc kill the build. I can remember one very rare case where that was not true.
-mcpu=p2 should always be safe, and I would not expect any problems with -O2.
