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:

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!
