bug#30879: Commit bc499b113 broke guix on address@hidden, improper <operating-system> field initialization

Hello Eric,

Eric Bavier <address@hidden> skribis:

That sounds a lot like regular ABI breakage: a new <operating-system>
field was added but gnu/tests/base.go wasn’t rebuilt, and thus was
expecting the previous struct layout.

Does “rm gnu/tests/base.go && make” suffice to fix this issue?

Thanks,
Ludo’.
