Who controls glibc?

My very very boring solution to this problem is to ensure that each site where you would emit an error has very minor variations in expression. Usually I try to make this be further information: "wrong endianness encountered in xxx" Here xxx sometimes isn't very user-digestible, but I try to make the first portion of the error as explicitly informative as possible and potentially put the xxx in parenthesis or similar. However, I have been known to use trivially different wording when the xxx approach isn't available.

As a a user, I'd prefer xxx to be some punchy vulgarity, but I think I'm in the minority.
