The previous patch adds ‘-D’ with the same meaning as in ‘guix shell’ so
it’s not available either.

I looked for other options and found ‘-P’, which is unused in ‘guix
build’ and ‘guix refresh’; it’s an alias for ‘--link-profile’ in ‘guix
shell’, an option that wouldn’t make sense in ‘guix build’.

Thoughts?
