Hi Thomas,

I'm currently integrating the Qemu test from toolchain builder (
https://github.com/bootlin/toolchains-builder/blob/master/build.sh) into
buildroot to check the consistency of the build and get some ensurance that
Qemu build process went successful for the various Qemu architectures. This
why I have enabled host-qemu. When compiling without using
"--disable-compile-warnings"; I got this message :

>>> host-libglib2 2.56.4 Patching libtool
>>> host-libglib2 2.56.4 Building
Failed build last output
  CC       libgio_2_0_la-glistmodel.lo
  CC       libgio_2_0_la-gliststore.lo
  CC       libgio_2_0_la-gapplication.lo
cc1: some warnings being treated as errors
Makefile:3927: recipe for target 'libgio_2_0_la-gunixconnection.lo' failed

A complete log errors is available here :

After disabling the warnings; most architectures passes the test with
success as shown at :
