cluttermm: M4 macros for gmmproc

[Debarshi Ray]

Is there any reason to get rid of the M4 macros used by gmmproc using
the following snippet?

# Remove files related to code generation
rm -rf $RPM_BUILD_ROOT%{_libdir}/cluttermm-0.8

I am curious since gtkmm24-devel does not remove them.

Happy hacking,
Debarshi
