Not many people cross-build native compilers at all.  Most people just build
their native compilers on the native system (it is not like building GCC is
so heavy, esp. if you don't bootstrap, which you don't do when you cross-
build it either), or build it in a qemu or similar to get things going.

Of course it *should* work, but it is no big surprise that very unusual
configurations encounter problems no one else does ;-)
