add hidden version of &errno accessor function
this significantly improves codegen in functions that need to access
errno but otherwise have no need for a GOT pointer.
we could probably improve it much more by including an inline version
of the &errno accessor function, but that depends on having the
definitions of struct __pthread and __pthread_self(), which at present
would expose a lot more than is appropriate. moving them to a small
tls.h later might make this more reasonable.
