Apple clang version 13.0.0 (clang-1300.0.29.30)
Target: x86_64-apple-darwin21.2.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
Machine: amd64
>Description:

./build.sh -U -u -O ../objects/amd64 -m amd64 build
The tools build fine. During a make build, the build fails in GCC 
external/gpl3/gcc/usr.bin/backend and it looks as if the host compiler is
being called instead of the toolchain:

>How-To-Repeat:

On MacOS Monterey on an intel Mac:
./build.sh -U -u -O ../objects/amd64 -m amd64 build

n/a
