Subject: fix pthread warnings

From: Stefan Assmann <sassmann@suse.de>

This patch declares prototypes of several functions to get rid of the
following compiler warnings:
./libpthread/linuxthreads.old/sysdeps/x86_64/pt-machine.h:44: warning: no previous prototype for 'testandset'
./libpthread/linuxthreads.old/sysdeps/x86_64/pt-machine.h:62: warning: no previous prototype for '__compare_and_swap'
./libpthread/linuxthreads.old/sysdeps/ia64/pt-machine.h:101: warning: no previous prototype for '__compare_and_swap_with_release_semantics'
