- Don't expect to find ellcc if building without modules (#188929).
    - New --with/--without rpmbuild flags:
    - xft: enable/disable Xft support, default disabled.
    - nox: enable/disable building the non-X version, default enabled
    - modules: enable/disable module support, default arch-dependent.
    - Re-enable XFontSet support for menubars for non-Xft builds (from
        openSUSE).
    - Move gnuserv to -common, gnudoit to base package, drop gnuattach.
    - Split ellcc and headers to -devel subpackage.
    - Drop unneeded libXaw-devel build dependency.
    - Move -nox "man page" to -nox subpackage.
    - Fix GTK build and glade detection for it.
    - Avoid -common dependency on ALSA.
