We use cross-compilation right now for mingw-* packages (for Windows).
However you cannot use cross-compilation to create a foo-*.armv7hl.rpm
package. That's because our entire toolchain, from RPM through Koji,
simply does not understand cross-compilation properly.
Well, the mock/rpm part is the smaller part of the issues (I use
customized mock setups on Fedora to build mingw-* and cygwin-* packages).
Solvable, but undoubtedly a ton of work for everyone.
The real issue would be to re-utilize "foreign native rpms" (here
*.arm.rpms) to install them in sys-roots on x86.
(Fedora's mingw*-toolchains are explictly packaged to fit into x86)
