no argument from me: my primary goal for GCC 15.1 right now is to avoid
breaking the build on Solaris.

That's one option, but maybe it's better the other way round: instead of
excluding known-bad targets, restrict cobol to known-good ones
(i.e. x86_64-*-linux* and aarch64-*-linux*) instead.
I've been using the following for this (should be retested for safety).
