[PATCH][s390] Fix some build warnings

[Siddhesh Poyarekar]

Hi,

Here's a patch that fixes some of the build warnings on s390x.  The
non-trivial change is the change in inclusion of sysdep.h from
"sysdep.h" to <sysdep.h> since the code otherwise ends up including
two different sysdep.h.

OK to commit?

Siddhesh

nptl/ChangeLog:

	* sysdeps/unix/sysv/linux/s390/jmp-unwind.c (_longjmp_unwind):
	Declare LOCAL_VAR as char.

ChangeLog:

	* sysdeps/s390/jmpbuf-unwind.h (_jmpbuf_sp): Declare SP as
	void pointer and cast to uintptr_t.
	* sysdeps/s390/s390-64/memcmp.S: Pick sysdep.h from include
	path.
	* sysdeps/s390/s390-64/memcpy.S: Likewise.
	* sysdeps/s390/s390-64/memset.S: Likewise.
