fixed variable clobber for thread & MP options added new

* configure.in: fixed variable clobber for thread & MP options
* app/Makefile.am: added new GIMP_MP_{LIBS,FLAGS} to compile &
link flags

The old configure would set the thread libs and then immediately
clobber them unless you enabled MP support.  This meant threads
but no MP would mean a no-compile if your pthread support is in a
separate library (not in libc).
