	pkgsrc/mk: bsd.pkg.mk pthread.buildlink3.mk
Added Files:
	pkgsrc/mk: pthread.builtin.mk

Log Message:
(1) Split out the native (built-in) pthread detection in
    pthread.buildlink3.mk into a separate file, pthread.builtin.mk,
    that is handled using the usual builtin.mk logic.

(2) If pthread.buildlink3.mk is included by a package Makefile, then
    automatically add the necessary compiler and linker flags to
    compile and link pthread-enabled/reentrant code.  For native
    pthreads, this means passing -pthread to the compiler and linker.
    For the userland pthread replacement, we pass -D_REENTRANT and
    -lpthread instead.

(3) Add PTHREAD_{CFLAGS,LDFLAGS,LIBS} in both CONFIGURE_ENV and MAKE_ENV
    when pthread.buildlink3.mk is included so that the configure and
    build processes can use these values.  Remove these definitions
    from bsd.pkg.mk since PTHREAD_* variables are all declared within
    pthread.buildlink3.mk.

XXX For now, PTHREAD_LDFLAGS is a superset of PTHREAD_LIBS until
XXX packages that use use PTHREAD_LDFLAGS can be fixed.
