To be real safe, you could set -prefix in the build configure to something
like /usr/local/avr.

But even if you haven't, don't worry, at least it will not override your
existing gcc.

The GCC guys have thought of that. Different targets uses different names.
So avr-gcc tools are all prefixed 'avr-' in the common /bin directory.
(Typically /usr/local/bin).
The install will also create gcc, ar, as etc... for the avr, but will copy
these in an avr sub-directory.
Just watch for what goes in /usr/local/include. The avr install will copy at
least 3 headers in there. These headers are not avr specific but matches
with the latest GCC distribution. But these should still work fine.
Backup you /usr/lib and /usr/include in case of doubt, but it works for me !
