Joseph, it appears that when building the cross compilers, there is no
way to restrict that to just the compilers for certain targets.  Is
that correct?  On one hand I can understand that, since that gives you
the maximum flexibility in what glibc libraries to build later but on
the other hand, that is a lot of cross-compilers.  I could see people
using this script to test the build of a particular platform that they
don't have access to as well as for testing multiple builds.  What do
you think about allowing a list of targets on the compilers build?
