Steps to reproduce: Start a guix build on a system without gcc.

There is some discussion in #21089:

Ah! This is because we now call build_CC and host_CC when determining our id_strings, and since the id_string variables are "immediate", any appending will also be evaluated immediately... Perhaps we can just set it to a dummy value when we're just downloading? Not sure what the best fix is here...

Right, small matter but if someone can come up with the right fix I'll apply it!

#21427 should fix this
