Issues when building with GCC 11

[bensuperpc]

I would like to build cpuinfo but i got an error while compiling googletest:

ninja: build stopped: subcommand failed.

I tested with Manjaro and dockcross, same issues. Used commands:

mkdir -p build
cmake -S . -B build -G Ninja
ninja -C build

GCC info:

Utilisation des specs internes.
