* sysdeps/powerpc/elf/libc-start.c [! SHARED]: Call

	__pthread_initialize_minimal and __libc_check_standard_fds to
	match the generic version.

	* sysdeps/powerpc/Makefile (CFLAGS-pt-initfini.s): New variable.

	* sysdeps/unix/sysv/linux/shmat.c (shmat): Add a cast to avoid a
	warning when INLINE_SYSCALL macro uses the __syscall_ipc function.

	* locale/localeconv.c (__localeconv): Cast -1 to char to avoid
	warnings on platorms where char is unsigned.
