	* sysdeps/sparc/sparc32/dl-machine.h
	(elf_machine_fixup_plt): During rtld bootstrap, always perform
	flushes as the kernel will emulate it when the underlying cpu does
	not implement flush.

	* sysdeps/unix/sysv/linux/sparc/sys/kernel_termios.h: Move...
	* sysdeps/unix/sysv/linux/sparc/kernel_termios.h: ...to here.

	* sysdeps/unix/sysv/linux/sparc/sparc32/__sigtrampoline.S: Remove.
	* sysdeps/unix/sysv/linux/sparc/sparc32/Makefile: No longer build
	trampoline code.

	* sysdeps/unix/sysv/linux/sparc/sparc32/clone.S
	(__clone): Branch to label .Lerror not __clone_syscall_error.
	(.Lerror): Fixup EINVAL setting.
	* sysdeps/unix/sysv/linux/sparc/sparc32/getgroups.c: New file.
	* sysdeps/unix/sysv/linux/sparc/sparc32/setgroups.c: New file.
	* sysdeps/unix/sysv/linux/sparc/sparc32/syscalls.list
	(__syscall_getgroups, __syscall_setgroups): Add.

	* sysdeps/unix/sysv/linux/sparc/sparc32/sigaction.c
	(__sigaction): Member name is k_sa_handler.  Use memcpy to copy
	around sa_mask data.

	* math/math.h: Include bits/nan.h when compiling for ISO C 9x.
