Comment (by kencu):

 by the way, Iain tells me gcc-10 is 100% good on 10.4 up, and it can
 bootstrap with gcc-3.4 or later.

 The only reason I have not enabled all that is our modifications to
 cctools make the gcc build using clang for the assembler sometimes, and
 that blows up the i386 builds. So I have written up some patches to
 disable the cctools assembler mods when building gcc using the ENV VARS we
 have for that, but it is -- messy -- to force gcc to obey ENV VARs during
 the build as it is specifically written to santize them out... so there's
 that.
