	* sysdeps/unix/sysv/linux/i386/pread.c: Removed, we can use the
	normal version now.
	* sysdeps/unix/sysv/linux/i386/pwrite.c: Likewise.
	* sysdeps/unix/sysv/linux/i386/pwrite64.c: Likewise.
	* sysdeps/unix/sysv/linux/mips/pread.c: Likewise.
	* sysdeps/unix/sysv/linux/mips/pwrite.c: Likewise.
	* sysdeps/unix/sysv/linux/arm/pread.c: Likewise.
	* sysdeps/unix/sysv/linux/arm/pwrite.c: Likewise.

	* sysdeps/unix/sysv/linux/pread.c (__libc_pread): Check
	endianness to decide how to pass arguments.
	* sysdeps/unix/sysv/linux/pwrite.c (__libc_pwrite): Likewise.

	* elf/vismain.c: Use test-skeleton interface.
	(TEST_FUNCTION): New macro.
	(do_test): Renamed from main.
