	* Makerules (libc_pic.os): Add $(LDFLAGS-os).
	* sysdeps/hppa/Makefile (LDFLAGS-os): Define.
	(CFLAGS-.os): Remove.

	* sysdeps/unix/sysv/linux/hppa/sysdep.h (CALL_MCOUNT): Update
	comment.

	* sysdeps/unix/sysv/linux/hppa/sys/ucontext.h (NGREG, NFPREG,
	gregset): Correct for new kernel definitions.
