Remove the ptw-% patterns

Browse Source 
Nothing depends on the PTW macro anymore, so the mechanism to define
PTW for recompliations of libc routines is no longer needed.  The
source files are still recompiled for the nptl directory, just without
the “ptw-” prefix.

(Reducing the number of pattern rules in sysd-rules is critical for
improving make performance.)

Remove support for compiling wrappers with PTW.
* sysdeps/nptl/Makeconfig: Drop ptw- support.
* nptl/Makefile (pthread-compat-wrappers): Define.
(libpthread-routines): Use pthread-compat-wrappers.
* sysdeps/unix/sysv/linux/alpha/Makefile
(libpthread-routines, libpthread-shared-only-routines): Remove
ptw- prefix.
* sysdeps/s390/nptl/Makefile
(libpthread-routines, libpthread-shared-only-routines): Likewise.
* sysdeps/ia64/nptl/Makefile
(libpthread-routines, libpthread-shared-only-routines): Likewise.
* sysdeps/nacl/Makefile (libpthread-routines): Use
pthread-compat-wrappers to filter the routines list instead of the
ptw- prefix.
