Did you try looking under the --prefix location?

Specifically in $HOME/gcc-7.1.0/bin

So do that then :-)

No, it's a terrible idea, but it only does that if you unpack the
source files in your home directory. I didn't think of that case when
writing the wiki page (I would never litter my home directory with
unpacked tarballs and "objdir", I'd do it in /tmp/ or a less permanent
location.)
