It seemed easiest to have one Makefile.version in nvidia-driver which defines the version number to avoid having to update it by hand in all the ports that depend on nvidia-drm

As we only need to pacify system compiler during the bootstrap, the following change to the gcc/configure is sufficient (i.e. amend the list of existing flags passed to the external compiler):

This seems cleaner to me than mangling the CXX but I won't insist.

this approach should be more future proof against newer clang versions.

Instead, I had to include the flag in CXX.
