I'm not talking about building glibc for 8051 (that would be kinda hard as an
average 8051 comes with 256 bytes of ram, and no I didn't forget an K or M there).
What I'm saying that using the same spec for sdcc and gcc makes no sense, iow
that when crossing to something not fedora using Fedora's specs as a base makes
no sense, because for example we might be dealing with a different compiler
(version).
Please read my reply to David Woodhouse.

Agreed, all that I'm saying is that the one spec file (with or without
overlays) might be a good idea for Fedora-Fedora crosses, but is not for
Fedora-Foo crosses.
