gcc receipe and architecture comment

[Riccardo Mottola]

Hi,

in the gcc receipe, which would be the last version that is supposed to 
run on solaris 9, I find this:

# We're not building GCC-4.7 on Solaris 9, because GCC-4.7 requires the
# sparcv8+ architecture.
# PACKAGING_PLATFORMS = solaris9-sparc solaris9-i386
PACKAGING_PLATFORMS += solaris10-sparc solaris10-i386

Why is v8+ a problem? I understand we support UltraSPARC only anyway, be 
it 32 or 64 bit.

I actually think to remember that the last operating system running on 
the "classic" SPARCs, is Solaris 8.

I wanted to upgrade gcc there.
