The GCC arch_canonicalize script was missed in the initial round of fixes.
There is a patch for that too.  And that patch may have to be backported to
older versions also.  This is going to be a mess for a while until we get
everything fixed.  Unfortunately us software guys can't do much about the
problem, as it is the RISC-V International ISA guys that are causing the
trouble.  They keep making changes without considering how it is going to
affect the software support.
