Sure. Find it attached. Tested with various GCC versions, clang, and tcc:
$ ./config.guess
x86_64-pc-linux-gnu
$ CC="gcc-version 8.5.0 -m64" ./config.guess
x86_64-pc-linux-gnu
$ CC="gcc-version 9.4.0 -m64" ./config.guess
x86_64-pc-linux-gnu
$ CC=$HOME/inst-clang/13.0.0/bin/clang ./config.guess
x86_64-pc-linux-gnu
$ CC=$HOME/inst-tcc/0.9.27/bin/tcc ./config.guess
x86_64-pc-linux-gnu
$ CC="gcc-version 8.5.0 -m32" ./config.guess
i686-pc-linux-gnu
$ CC="gcc-version 9.4.0 -m32" ./config.guess
i686-pc-linux-gnu
$ CC=i686-linux-gnu-gcc-10 ./config.guess
