Sorry but I don't understand what's the issue you are trying to fix.
I've built some gcc 9.x toolchain without any issue.
Can you give some details please.

Best regards,
Romain

I started a build using your config file. I just disabled ccache because it can
cause weird issues... Maybe you can try without ccache.

So far the build succeeded here.

Can you try with qemu_arm_vexpress_defconfig

$ make qemu_arm_vexpress_defconfig
$ make toolchain

If something go wrong, then it's a problem on your host.

Best regards,
Romain

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
