Running the glibc testsuite - which is actually a pretty good test for
the ifunc code. There's no functionality in the aarch64 port yet that
actually uses this yet so I couldn't test that. The only screw up that
the testsuite does not find is failing to pass hwcap correctly to the
resover, but I pretty intensively stared at that code and seen as
everything goes through elf_ifunc_invoke I am happy that it should
work in practice.
