So
- Does this mean that mass packaging change will occur?
- Currently rpmbuild detects pkgconfig .pc dependencies, so for -devel
   packages containing pkgconfig .pc file now we usually don't have write
   dependency for another -devel subpackage like "Requires: foo-devel"
   explicitly (as rpmbuild automatically adds "Requires: pkgconfig(foo)")
     (and I guess we shouldn't write such explicit requires when possible
      and let rpmbuild handle such dependencies automatically)

   If dependencies between (non-arch) -devel packages must be changed to
   explicit arch-specific, it means that rpmbuild should also be changed
   to add arch-specific pkgconfig Provides / Requires (e.g.
   pkgconfig(x11)(x86-64) instead of current pkgconfig(x11)) ?

- And as far as I am correct this also applies to other virtual Provdes/Requires
   rpmbuild will automatically add.
   - For example perl(BDB) devendency on perl-Coro.x86_64 will be satisfied by
     perl-BDB.i686? Then this type of all virtual provides / requires rpmbuild
     will handle must be changed??

   Unless I am wrong to make things consistent such changes on rpmbuild must
   be required. However is this actually we want?
