For example to prevent Xen being installed on any s390x
xen:
default-s390x:
deb: libxen-dev
Fedora: xen-devel
Or the inverse to only install Xen on x86_64 on Debian, but allow
it on all archs on Fedora
xen:
deb-x86_64: libxen-dev
Fedora: xen-devel
Note that the architecture specific matches are considered after
all the non-architcture matches.
The mappings are updated to blacklist libnuma on arm6/7 for Debian
since it is not built for those archs. xen is whitelisted to only
be used on x86_64, arm7 and aarch64 for Debian, since the majority
of other architectures don't support it.
The dockerfile generator is updated to apply arch filtering based
on the host arch.
The ansible playbook is not actually implementing support for
non-x86_64 architectures in this commit. It is just hardcoding
x86_64, which is enough to ensure the changes in the mappings.yml
file are a no-op initially.
