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.

The patch touches a minor (well, not that minor, but perhaps only
rarely encountered) bug in the powerpc dynamic linker.
The problem is that addi is called in inline assembly, but there is no
restriction on the second argument. In powerpc assembler, if the
second argument to addi is r0, it is taken as the value 0, not the
contents of r0. This happened to me, making the stack pointer 0 on
the invocation on the application.

to the relevant section in 0.9.23.

Removing those instr. comes with a very big performance
penalty. To flush the dcache you will have read up to 8KB
dummy data and to invalidate the icache you will have to
execute up to 16KB nops. I don't know of any other way from
user space.
hmm, actually I think it will work reliable to perform a
store to the same page(s) as the dcbst/icbi will act on. That
way you will make the DTLB Error happen(if any) prior to the
dcbst/icbi. The worst thing that can happen then is a regular
DTLB Miss and that works for dcbst/icbi.
You will have to lookout for if dcbst/icbi crosses a page
boundary. Then you will have to perform a store to both
pages.
