Directions for gcc 7.5 are incorrect

[programmingkidx]

I downloaded gcc 7.5 from here: https://github.com/Scottcjn/ppc-compilers/tree/main/gcc7.

The directions say this:

cd /usr/local
sudo tar xzf gcc7-7.5.0-tiger-ppc.tar.gz

What is expected is gcc-7 to be installed here:
/usr/local/bin/gcc-7 - C compiler
/usr/local/bin/g++-7 - C++ compiler
/usr/local/Cellar/gcc7/7.5.0/ - Full installation

What really happens is gcc-7 is installed here:
/usr/local/gcc7/7.5.0/bin/gcc-7

I ask that the directions on the web page be updated.
