Comment (by ryandesign):

 Reading through the crossgcc-1.0 portgroup, it looks like it just runs
 ./configure and make once. Reading various documents*, I don't think
 that's enough to build a functional cross compiler. We run ./configure
 with --target set to the cross-compiling target, which is indeed what we
 need to do to build gcc. But we apparently also need to run ./configure
 with --build set to the build machine target and --host set to the cross-
 compiling target in order to build a proper glibc.
