A user or administrator can install any version of gcc they like, in any
location they like.  The concept of "default" isn't really well defined.
The closest you can get is that the "default" for a given system is
probably /usr/bin/gcc, or at least the gcc that's in the user's default
$PATH (not all distributions necessarily distinguish between /usr/bin
and /bin).

If there's a /usr/local/bin/gcc that differs from /usr/bin/gcc, it's not
clear which of them is the "default".  Probably /usr/bin/gcc is the
default for the distribution and /usr/local/bin/gcc is the default for
that particular machine, or perhaps a collection of machines that are
administered together.
