Hi Peter,

I suggest you to take a look to:
  https://lists.gnu.org/archive/html/guix-devel/2023-10/msg00014.html
Because I'm the ^1 in that email and you can see the problems I've
had with ARM (it was a problem with RP4020).

The current toolchain is not able to find the stdlib.h and this is a
huge inconvenience. I didn't manage to solve it but the email I'm
linking there is really promising (I didn't have the time to test,
but the author told me he was able to solve my problem using his
toolchain).

We should fix this in Guix, but right now it just doesn't work.

Cheers,
Ekaitz
