Sounds good to me. If GCC >= 11 has fixed it, should we instead test
for GCC < 11, i.e. it could help catching future new regressions like
the linked GCC bug, if I understand correctly, right? Of course, that
could be done for the next cycle, since this one minimizes the
original change w.r.t. v6.2.

By the way, missing space on the title (`arch:um`).

Cheers,
Miguel
