Ok, I reproduced the issue by enabling again ccache.

It fail with:

/home/naourr/buildroot/test/toolchain/build/host-gcc-final-9.3.0/build/./gcc/xgcc
-B/home/naourr/buildroot/test/toolchain/build/host-gcc-final-9.3.0/build/./gcc/
-xc -nostdinc /dev/null -S -o /dev/null -fself-test=../../gcc/testsuite/selftests

make[4]:
/home/naourr/buildroot/test/toolchain/build/host-gcc-final-9.3.0/build/./gcc/xgcc:
Command not found

For some reason, xgcc is not built when ccache is used...

Best regards,
Romain
