runtime: make runtime·usleep and runtime·osyield callable from cgo callback

runtime·usleep and runtime·osyield fall back to calling an
assembly wrapper for the libc functions in the absence of a m,
so they can be called in cgo callback context.

Ugh, is it possible to --cc and -r everybody in a single hg mail invocation?
Multiple --cc options seem to be silently discarded.

Yes, -cc a,b,c

LGTM

This is getting worse and worse. Please make sure the damage remains contained
to _solaris files.

Please don't submit yet, TLS changes broke it, working on it.
