	* sysdeps/unix/arm/sysdep.S (syscall_error): Optimise a little.
	[__LIBC_REENTRANT]: Unify PIC and non-PIC cases.

	* sysdeps/unix/sysv/linux/arm/sysdep.h (PSEUDO): Remove .type
	directive.
	(PSEUDO_RET): Use SYSCALL_ERROR in place of __syscall_error.
	(SYSCALL_ERROR): New.
	(SYSCALL_ERROR_HANDLER) [NOT_IN_libc]: Provide local copy of error
	handling code.
	(INTERNAL_SYSCALL): Define.
	(INLINE_SYSCALL): Use it.
	(INTERNAL_SYSCALL_ERROR_P, INTERNAL_SYSCALL_ERRNO): Define.
	* sysdeps/unix/sysv/linux/arm/socket.S (__socket): Use
	SYSCALL_ERROR in place of __syscall_error.

	* sysdeps/ia64/bits/byteswap.h [__GNUC__ >= 2] (__bswap_16,
	__bswap_32, __bswap_64): Put x into temporary variable
	to avoid warnings.
	[!__GNUC__] (__bswap_16, __bswap_32, __bswap_64): Change into static
	(inline) functions.
	* sysdeps/s390/bits/byteswap.h [__GNUC__ >= 2] (__bswap_16,
	__bswap_32, __bswap_64): Put x into temporary variable
	to avoid warnings.
	[!__GNUC__] (__bswap_16, __bswap_32, __bswap_64): Change into static
	(inline) functions.
	* sysdeps/i386/bits/byteswap.h [!__GNUC__] (__bswap_16, __bswap_32):
	Likewise.
