bug#41091: can't build external gcc |

Many projects (Buildroot, coreboot, Yocto) require building a toolchain.
Every time it tries to build it (I've checked Buildroot and coreboot) it fails
with the following errors:
In file included from ./bconfig.h:3:0,
from ../../gcc/gengtype-lex.c:4:
./auto-host.h:2396:16: error: declaration does not declare anything
[-fpermissive]

Switching gcc versions doesn't help.
One can find a simple way to reproduce in buildroot.txt, build-gcc.log provides
a complete log.
Looking forward for your help. Thanks!
