commit 52d37d2c916865ff81da4ff923ae5cfcdc16c2c3
Author: Mike Frysinger <vapier@gentoo.org>
Date:   Sun Jun 13 01:54:48 2021 -0400

    sim: drop arch-specific config.h
    
    All of the settings in here are handled by the common top-level
    config.h, so drop the individual arch-config.h files entirely.
    
    This will also help guarantee that we don't add any new arch
    specific defines that would affect common code which will help
    with the effort of unifying them.
