I would like to build the kvx-xgcc to compile and test the linux
kernel, but it reported a compile error.
I wonder what version of gcc you are using.

My build environment:
VERSION="20.04.2 LTS (Focal Fossa)"
gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04)


Compile error:
$ ./build-kvx-xgcc.sh output
