I'm not sure if this is considered a bug or not, but the solution to
your problem is to use --check. Using your test file running:
guix build -f test.scm --check
should run the build one time, and compare the output with what is in
the store. Then:
guix build -f test.scm --check --rounds=2
should run the build twice, and check against the output that is already
in the store.
It's a bit confusing, but --rounds only applies if there is actually a
build to do, whereas --check forces a build and compares against the
store.
