--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Don't do that then. It's documented to not be supported:
First, we @strong{highly} recommend that GCC be built into a
separate directory from the sources which does @strong{not} reside
within the source tree. This is how we generally build GCC; building
where @var{objdir} is a subdirectory of @var{srcdir} should work as well;
building where @var{objdir} == @var{srcdir} is unsupported.
