Theoretically, you will only need the debuginfo packages if you have a 
crash and want to debug it. It will not be something that most users 
install.

It is already there. I added support for it a few months ago.

I wasn't very clear about what I wanted with the makefiles. Basically, 
this will be an optional post-build step. The way I am leaning towards 
at the moment is that "make install" will install with full debugging 
information, but "make install && make install-debuginfo" will strip the 
debug info into separate files and install it. AFAIK, the feature has 
been stable for a year and a few distros are making full use of it. 
Fedora definitely provides -debug packages that have the separate debug 
information.
