* sysdeps/unix/sysv/linux/i386/sysdep.h (PSEUDO): Use
SYSCALL_PIC_SETUP before jumping to syscall_error.
* sysdeps/unix/i386/sysdep.h (SYSCALL_PIC_SETUP): New macro.
(PSEUDO): Use it before jumping to syscall_error.
* sysdeps/unix/i386/sysdep.S [! PIC]: Don't find GOT address;
expect it in %ebx on entry. Pop old %ebx value off stack after
using it.
