Yes, for a musl system, that's wrong.
The problem may come from your environment. Which of the environment
variables CC_FOR_BUILD, HOST_CC, CC, CONFIG_SITE did you have defined,
and to which values?

The mailing list is https://lists.gnu.org/mailman/listinfo/config-patches .
The current code in config.guess is a heuristic (that has been working
on Alpine Linux up to 3.13), because the musl libc people refuse to have
their libc identify itself. [1]
