Build: add make rpms target and convenience script makerpms.sh

make rpms and ./makerpms.sh will produce the same RPM packages. The
advantage of makerpms.sh is that it will take care of initial
autoreconf & configure phases as needed.

rpm-build-4.13.0-1.fc24.x86_64 broke parallel build of RPMs.
If you get error
  INTERNAL: Exiting with 1 jobserver tokens available; should be 8!
undefine the MAKEFLAGS variable and do not specify neither -j nor -l.
