I would be happy to provide a single script tailored for this purpose.
Total runtime for the script would be under a day on a 1GHz machine, I think.

What's the appropriate list of targets?  My first guess is:
   arm, i686, ia64, m68k, mips, powerpc750, powerpc970, s390, sh4, x86_64

What's the desired output format?  Something similar to
http://kegel.com/crosstool/crosstool-0.28-rc37/buildlogs/0.28/
(but for only one version of gcc/glibc/binutils), I imagine.
