crossgcc/gnat.patch: Never treat warnings as errors
We used to disable individual warnings that are expected when building
our GCC version with a newer one. Not all warnings can be disabled
indvidually, though, and it's much easier to simply allow warnings.
As a plus, we get the warnings in the log (in case anybody would ever
look into it).
Partially fixes building with host GCC 12.1.
