Xinpeng Liu via Nick Desaulniers sent a description of the problem and a
patch so I think I'll be able to fix this.  However...

...as I said before I think you definitely need to coordinate with the
DRM people - Nick Desaulniers' patch 0f0727d971f6f (drm/amd/display:
readd -msse2 to prevent Clang from emitting libcalls to undefined SW FP
routines) breaks in places that don't have merge conflicts due to this
change.  I wouldn't rely on the merge going well if things are sent
as-is, the only reason this one showed up was that other people were
adding new files to the Makefile.

I've CCed Nick.
