description:
mk: Stop using XCode binaries on Big Sur.

These no longer support being executed via a symlink, failing with errors
such as:

  xcode-select: Failed to locate 'gmake', and no install could be requested

This breaks the entire .tools/bin directory, so we just have to avoid them
and use tools from pkgsrc instead.

It's likely a lot more will need to be added to this list, but this is
enough to get devel/cmake building at least.
