Maybe using a macro defined closed to fixup-libtool-files and calling
this macro here instead of '$(Q)rm ...' will help.

I prefer having overwrite detection quite stupid. It checks for
overwrites without any exception.
Adding exception now in the detection mechanism is opening the door to
more and more exceptions.
