Does it strike you that perhaps this could be fixed more quickly in
Alpine ldd instead? The problem affects Alpine Linux 3.10, but not
later versions, it seems, and 3.10 becomes unsupported after May 1
next year. By the time this fix is propagated into packages that
include config.guess, I imagine most users will have upgraded to
>3.10.

The command line interface of system programs should remain stable.
