GUIX_BUILD_OPTIONS is intended for options that related to building,
namely those listed in ‘%standard-build-options’ in (guix scripts
build).

Conversely, ‘--no-grub’ is specific to ‘guix system’.

Same issue: the manual is somewhat vague, but ‘--system’ is not in
‘%standard-build-options’.

‘--system’ was intentionally not added to ‘guix package’ on the grounds
that it wouldn’t be very useful to install binaries built for another
system in a profile.

Now, I agree that the situation is different on “multi-personality”
systems, so maybe we should revise that choice?

Thoughts?
