--- Comment #9 from Hin-Tak Leung <htl10 at users dot sourceforge.net> ---
Did the change make it into 4.9.2? I recently tried that
and found that I need the explicit --sysroot:
https://gcc.gnu.org/ml/gcc-testresults/2014-11/msg00268.html

Otherwise it fails during the stage1-fixincludes stage.
(luckily I saw the tips and reference to this bug report
in the older buildstat).
