Subject: Paul Mundt <lethal@linux-sh.org> writes:

This patch adds the libpthread backend bits for sh64. As noted previously,
we can't inline things like the testandset() in pt-machine.h as we need to
use a completely different ISA / CFLAGS in order for this to work.

As a result, this patch is somewhat of a RFC as well to see what people think
of the libpthread/linuxthreads/sysdeps Makefile approach, etc. The approach
I've taken currently has been to provide a sysdeps/Makefile with a note that
TARGET_ARCHs that want build rules can simply add themselves into the list of
matching architectures to add to the subdir rule for. This probably isn't
the cleanest solution, but it's quite transparent and works quite well.
