[LLVMdev] Bad gcc versions

[Chuck Zhao]

I think the problem is also platform dependent,  and I have been trying 
to come up with the known-good list of build gcc/g++ on various 
platforms for a long time.

E.g.,
on Debian-32 5.0.5 (Intel): gcc-4.0.4, gcc-4.1.2 are bad, gcc-4.2.4 
seems to be fine.
on Debian-64 5.0.4 (Intel): the default gcc (4.3.2) seems to be fine.

We may want to cover this for a wide range of possible platforms. The 
ones listed in the Getting Started Guide is in complete.
