I use segher's buildall script.

buildroot doesn't look useful. I seems to build to only build one target
at a time, and build a crapload of cross-userspace, I just want a
compiler. And I'm most certainly not going to build the compilers one
by one.

The buildall script I put to work and after about an hour I have however
many of the 20+ targets that build with gcc.git and binutils.git cross
compilers.
