While the patch allowed me to cross-build a native gnat-7, native
builds unfortunately currently fail with obscure linker errors [1]:

I have investigated the issue but so far I haven't found anything obvious
that explains the problems. I'm not 100% sure whether this might be something
that needs to be fixed in the packaging or whether this is another upstream
bug.
Either way, cross building a native gnat-7 with my patch works, a full
native build fails as shown above.
