libgo: fix build when using -enable-static=no

    
    With -enable-static=no we don't build non-pic objects, but libgotool.a
    is built from non-pic objects.  Build the packages that go into
    libgotool.a in static mode in all cases.
    
    Also ensure that internal test packages are built, since nothing
    explicitly depended on them.
