 --program-prefix/--program-suffix for 'gcc' (AVR build)

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:

$(target_noncanonical)-gcc-$(version)$(exeext) )
  	-if [ -f gcc-cross$(exeext) ] ; then \


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.
