Most Linux users should install gcc as part of a package.
When you install gcc or glibc packaged as an .rpm or .deb package
(as part of a Linux distribution), it should of course go in /usr.

When you build gcc from source, it should *by default* install
in /usr/local, *just like all other GNU packages*.

The paths should be different in the two situations.

If you (or a Linux package maintainer) want to make make a binary
release, you should configure it with --prefix=/usr - just like all
other GNU packages.
