* 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.
