I've queued this up as fixes for 5.4, but I ended up making quite a few
additional changes to address some other issues and minor inconsistencies
I ran into. In particular, with my changes, you can now easily build the
kernel with clang but the compat vDSO with gcc. The header files still need
sorting out properly, but I think this is a decent starting point:

Please have a look.
