Note that this fails on "buildSRPMFromSCM", i.e. when creating srpm,
and not on "buildArch" (armv7hl, i686, x86_64), where rpmbuild the newly
created srpm is executed.

So when using mock, usually srpm is already there on your local disc.
But on koji, first koji tries to "create srpm" from SCM (git repository),
and when creating srpm, koji uses:

/usr/bin/rpmbuild -bs --target noarch --nodeps foo.spec

i.e. creating srpm is always done as noarch. Then after creating srpm,
arch-dependent (sometimes independent) rpmbuild foo.src.rpm is executed.
