# force the target arch for the tests

# By default, the packages would be built for the arch detected by rpm-build
# (rpmbuild --eval %_arch). On installation, they would be compared
# by rpm for compatibility with the arch detected by rpm. Currently,
# the mismatch in the detection between rpm and rpm-build can lead to problems,
# at least, on armh. So, we set the target by force to a value that must work.
