Added a script to create bits/syscall.h for each arch.
NOTE!!! This is run by "make -C libc/sysdeps/linux/$(TARGET_ARCH) headers"
in the main Makefile, but I only changed libc/sysdeps/linux/i386/Makefile
as I had no way of testing it for the other archs. Various arch maintainers,
please check and update the corresponding Makefile... or report bugs ;-)...
appropriately. You'll also want to "cvs del" syscall.h and add it to
a .cvsignore in $(ARCH)/bits.
Also added a define to uClibc_config.h, __UCLIBC_USE_UNIFIED_SYSCALL__, and
moved i386 unified syscall stuff out of common and into i386/bits/syscalls.h.
