Splitting foo2zjs

[Till Kamppeter <till.kamppeter@gmail.com>]

OdyX, you have split foo2zjs into printer-driver-foo2zjs and
printer-driver-foo2zjs-common telling that you want all arch-independent
files being shared across architectures. This saves some disk space in
the build server infrastructure (there should be plenty of disk space)
and on the user side it is probably without any benefit as nowadays no
one shares a system disk partition between several computers (which can
be of different architectures). So for me it looks like that it makes
building and updating more complicated without real benefit. Or what are
the real advantages?
