This is on the roadmap, and there's a pending patch on the list, but
it still needs some changes before it's ready to commit.

Are you aware of anything else blocking support for these libs? It
might be worth doing a symbol listing and checking it against
functions that might have glibc extensions we don't support or the
minor ABI mismatches (non-*64 funcs for 32-bit, or regexec regoff_t
for 64-bit).
