Makefile.in: pass -Wno-unused-parameter explicitly

One would think that -Wno-unused would suffice.  However, in gcc 4.8.2
it doesn't, even though it does in 4.7.2.  This is arguably a bug in
gcc (filed as Debian #747345), but it looks like we will have to work
around it.

This avoids this error message:
 util.c:202:29: error: unused parameter 'phase' [-Werror=unused-parameter]
and several like it.
