Comment:
The multiarch detection works on Ubuntu 11.10, x86-64, and Ubuntu 12.04,
i386. I also tested this on Arch Linux, which just upgraded to gcc 4.7,
and it correctly decided to install our gcc spkg.
Note that Ubuntu 11.04 (with gcc-4.5.2) uses the multiarch stuff, and your
script misses that because it looks for version 4.6.*. However, the
compilation seems to work properly. (That was Ubuntu's first multiarch
release, so perhaps the "old method" still worked there?) Also, I don't
think we need to prioritize support for that release.
So, positive review, unless someone objects to building our gcc if the
system gcc is older than 4.4.
