This should have no effect on the compiled code, but it is wholly untested.
Please verify that it indeed does not change the code.  Feel free to commit
it yourself if you want to, or I'll do it on your approval.
What I use to verify no code changes is:

	$ make -j... # build before applying patch
	$ mkdir =stock
	$ cp libc.so =stock/
	... apply the patch ...
	$ make -j... # build after applying patch
	$ diff -u -I '.*file format.*' <(objdump -rd =stock/libc.so) <(objdump -rd libc.so)	


Thanks,
Roland	


	* sysdeps/unix/sysv/linux/microblaze/arch-fork.h: New file.
	* sysdeps/unix/sysv/linux/microblaze/nptl/fork.c: File removed.
