As we were discussing in the channel, maybe it's OK for these binary
installs to claim "/opt/gnu".  Then we expose the profile in /opt/gnu,
so you would run Guile as /opt/gnu/bin/guile.  Additionally you could
actually build against that Guile, which would be pretty neat.  If the
user untars multiple guix packs, /gnu/store easily absorbs the union,
and /opt/gnu will adjoin any new profile directories/files and replace
any overwritten links.

We would have to make sure the union directory in /opt/gnu has all real
directories and only symlink files, as per the recent patch on
guix-devel.
