	* 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.

+{ZW} This happens when you have installed glibc as the primary C library but
+have stray symbolic links pointing at your old C library.  If the first
+`libc.so' the linker finds is libc 5, it will use that.  Your program
+expects to be linked with glibc, so the link fails.
+
+The most common case is that glibc put its `libc.so' in /usr/lib, but there
+was a `libc.so' from libc 5 in /lib, which gets searched first.  To fix the
+problem, just delete /lib/libc.so.  You may also need to delete other
+symbolic links in /lib, such as /lib/libm.so if it points to libm.so.5.
