Well, it doesn't have to go in the .spec file. But it would be nice to
be able to change the performance-tuning flags used on libgcj without
having to hack the Makefiles.
BTW, if we drop specs, how do you ensure that client applications get
built with the same performance-tuning flags as libgcj? Do you
hard-compile that option set into the compiler? I guess that would be
fine -- but in that case it would be nice to be able to add to this
hard-compiled set with a configure option.
