Yes, it means that =E2=80=98linux-module-build-system=E2=80=99 does not ret=
urn a bag
when cross-compiling.

See =E2=80=98gnu-build-system=E2=80=99 for how to support cross-compilation.

In the meantime, Mathieu, perhaps you can test system cross-compilation
by using a =E2=80=98computed-file=E2=80=99 (instead of a package) as a fake=
 package
providing modules?

Thanks,
Ludo=E2=80=99.
