Add architecture argument for the buildroot chroot
This allows to run the following commands:
pmbootstrap chroot --buildroot x86_64
pmbootstrap chroot --buildroot aarch64
pmbootstrap chroot --buildroot armhf
and
pmbootstrap chroot --buildroot device
which is also the default if no argument is passed.
The device
gets replace with the architecture of the device selected in pmbootstrap init
, which is the same behavior as before.
Also added a simple test case that runs uname -m
in every chroot and checks the output.
