# yeah it's a bit hacky setting the arch here -- but the issue is that m1n1 doesn't have a cross compile option
# so it'll build an aarch64 version regardless -- which isn't compatible with the
# traditional rpm build process which will attempt to cross compile it by setting the target ARCH
# the following line causes the rpm to be named *.aarch64
%define _target_cpu aarch64
