libpthread: linuxthreads.old: Allow building for no-legacy-syscalls ABI
Since NPTL port to an ARCH can be non-trivial, we must allow the legacy
pthread lib to be built for the common-generic syscall ABI
Note that only linuxthreads.old is allowed, since "newer" linuxthreads
relies on sysctl which the ABI no longer provides.
