#429 Patch to separate Makefile arch-dep and arch-indep install

[Thijs Kinkhorst]

Hello!

When packaging Mailman for Debian, we create different
packages for architecture-specific files and
architecture-independent ones. For this we need to
separate those install steps.

Attached patch adds that possibility to the Mailman
makefile; it adds two new targets "do-arch-install" and
"do-indep-install"; the old "doinstall" remains and
calls both new targets.

I think this might be useful to others who wish to
separate arch-dep and arch-indep files and it doesn't
hurt other users. That's why I request this patch to be
included into Mailman.
