the easiest way to run the glibc tests is to build it natively
(because the test system has assumptions about the host env that
is hard to match with the ssh+nfs cross test setup).

currently the test system depends on perl (for header conformance
tests and memory leak tests) which is already a pain.

python is another hard to build dependency and you have to make
sure that python language changes don't affect the behaviour.

i think this is not a critical issue since the build can succeed
without i8*, but it is worth noting.
