* Makefile (sysdeps_headers): Add spin-lock-inline.h.
(SYSDEP_PATH): Move sysdeps/i386 right after
sysdeps/$(MICROKERNEL)/i386.
* include/pthread/pthread.h: Include <bits/spin-lock-inline.h>.
* sysdeps/i386/bits/spin-lock.h: Move inlines to...
* sysdeps/i386/bits/spin-lock-inline.h: ... new file.
* sysdeps/mach/bits/spin-lock.h: Move inlines to...
* sysdeps/mach/bits/spin-lock-inline.h: ... new file.
