Hi,
I cc Nathanael Nerode since according to MAINTENERS he one of the people
in charge of Makefile.in.
I filed a bug against make install which does not honor
--program-prefix/--program-suffix for the driver 'gcc' while building
for target AVR (maybe others too). In a particular case
(--program-prefix='avr-' --program-suffix='-4.7.1'), gcc is not
installed at all in $(DESTDIR)$(bindir).

By taking a closer look at the output of 'make install' it appears that
gcc is in fact installed with the requested name, but removed just
afterward:
-------8<----------
rm -f /tmp/gcc-4.7.1/bin/avr-gcc-4.7.1
/usr/bin/install -c xgcc /tmp/gcc-4.7.1/bin/avr-gcc-4.7.1 (install)
rm -f /tmp/gcc-4.7.1/bin/avr-gcc-4.7.1 (delete )
-------8<----------
I fixed the problem by swapping the two corresponding lines in the
target 'install-driver' of the file ${GCCSRC}gcc/Makefile.in:

With that patch, gcc is installed both with its canonical name
(avr-gcc-4.7.1) and with the requested program -prefix/-suffix like all
other binaries.
