FW: NPTL support on PPC32 (MPC5200) ?

[Jim Freeman]

I find that I have to apply the attached patch to

	contrib/crosstool-0.28-rc34-nptl_fixes.patch

or else I get the following error:

	+ cp
	/opt/src/crosstool-0.28-rc37/build/powerpc-8540-linux-gnu/gcc-3.4.2-glibc-2.3.3/glibc-2.3.3/nptl/sysdeps/unix/sysv/linux/ppc/bits/pthreadtypes.h
	/opt/src/crosstool-0.28-rc37/result/powerpc-8540-linux-gnu/gcc-3.4.2-glibc-2.3.3/powerpc-8540-linux-gnu/include/bits/pthreadtypes.h
	cp: cannot stat
	`/opt/src/crosstool-0.28-rc37/build/powerpc-8540-linux-gnu/gcc-3.4.2-glibc-2.3.3/glibc-2.3.3/nptl/sysdeps/unix/sysv/linux/ppc/bits/pthreadtypes.h':
	No such file or directory

[ ARCH=ppc, but dirname = powerpc/ ]

The build hasn't finished yet, but at least it no longer dies at this
spot.
