Eh?  This is the first time anyone's ever mentioned that.  Thanks! 
It's obvious how much cross-compilation means to me.

(You realise there are *hundreds* of CC=gcc lines in current Guix, 
right?)

Don't get me wrong: I love that Guix still cares so much about 
cross-compilation, and the tremendous effort I see in the logs 
every month to make it work better, when (at least a few years 
ago) it was all the rage to declare it dead since VMs exist or 
something.

I agree that handling (only) standard GNU variables[0] in the GNU 
build system makes sense.

I'll add the snippet of power.

Kind regards,
