Erm... AFAIK there are two goals: 
1) Switch MESA from gcc to Sun Studio
2) Reduce the size of the MESA binaries

I'm not sure whether [2] can (currently) be better archived using a gcc
build with options "-Os" and "-fmerge-all-constants" (since Sun Studio
has currently no equivalent for gcc's "-fmerge-all-constants" and
somehow isn't able to reduce the code size used by |inline| functions
which are only consumed once (which is IMO a bug)).
Maybe the next time the LiveCD runs out of space someone should look at
MESA again...

Ok... ;-(
