Makefile.in (pexecute.o): Use pexecute.c from libiberty.

        * Makefile.in (pexecute.o): Use pexecute.c from libiberty.  Provide
        explicit rules for building.  Similarly for alloca, vfprintf,
        choose-temp and mkstemp, getopt, getopt1, and obstack.
        (INCLUDES): Add $(srcdir)/../include.
