Can you rephrase the bit about the libnosys condition; should
that part of the patch be applied with a big #ifndef HAVE_MKDIR
around the guts of mkdir.c or what?

I was under the illusion that all targets that care already did
link with libnosys as a fallback, but with that prerequisite
gone I agree conditionalizing the call makes better sense.

This would work for me, too...but IIUC the reent.h part of the
patch I posted would still be be needed.
