jmpbuf-offsets.h

[Roland McGrath]

It's really only for internal use, so there is no need for architectures to
add one if they have no code that wants it.  I made bits/setjmp.h suck it
only to be lazy and not update the internal uses.  But I forgot that the
stub file would not be found in setjmp.  I've fixed it now to just avoid
the shenanigans and use jmpbuf-offsets.h directly only where it's needed.


Thanks,
Roland
