I have trouble creating an override file that works for all
architectures.

On some architectures, lintian (correctly) issues:
mksh: statically-linked-binary [bin/lksh]
I can override this.

But on other architectures, lintian (wrongly) issues…
mksh: shared-library-lacks-prerequisites [bin/lksh]
… instead (for static-PIE executables).
I can override this as well.

But when I put in both overrides, I get one of…
mksh: mismatched-override statically-linked-binary [bin/lksh]
mksh: mismatched-override shared-library-lacks-prerequisites [bin/lksh]
… obviously.

I tried putting…
mksh: mismatched-override statically-linked-binary [bin/lksh] *
mksh: mismatched-override shared-library-lacks-prerequisites [bin/lksh] *
… but they did not take.
