Comment (by kencu):

 upstream tested and verified the build of gcc9 on all systems from 10.4
 PPC up, so I'm not exactly certain what is causing this at present.

 It could be us -- our modifications to cctools to use a newer clang as the
 assembler has inserted some Heisenbugs into the build of gcc (it won't
 build i386 due to this, for example).
