I meant if the bad generated code would affect any package built with
libgsasl. If things would fail, etctera. Then, I looked at the binutils
bug and realized this was only a linker bug and there was no bad
generated code.

Well, since we know exactly where the problem lies and that this will
not affect any other Debian package, I think that's OK.

Please, go forward and disable the test in mips.
