This looks good.  I'll approve the changes to the GCC subdirectory.
Please also poison HOST_WORDS_BIG_ENDIAN and BYTEORDER in system.h.

xm-*.h files are only pulled in if they are explicitly mentioned in
config.gcc, so neither m32r/xm-m32r.h nor m32r/xm-m32r.h is being
used, despite having been accidentally restored.  (Don't be misled by
the "*-local-*" stanza, which should probably be removed - anyone
seriously coding a local GCC port is going to have to write a real
config.gcc stanza anyway.)

Accordingly, I'll preapprove a patch that removes both these revenant
xm-*.h files.
