description:
Add alternatives.mk, a file used to manipulate the alternatives system.
A package can optionally provide an ALTERNATIVES file which contains pairs
of wrapper/alternative, one per line.  The file is then used by the install
and deinstall scripts to register the alternatives and to create the
appropriate wrappers.

Make bsd.pkg.mk include this new file.  This happens unconditionally to
keep all the alternatives logic in an independent file.  Otherwise, some
of the stuff could have to be moved to bsd.pkg.mk, breaking consistency.
