> [PATCH] gnu: ephemeralpg: Fix cross-compilation.

There is already a patch for that:

<https://issues.guix.gnu.org/49327#8>

and (a rebased version of) it effectively has already been applied:

<https://issues.guix.gnu.org/49327#150>

I guess you could copy it from c-u to master if you don't want to wait 
for the c-u merge, but please use the search function at 
<https://issues.guix.gnu.org/>:
