Thanks for the warning, Khem, but I'm well aware of this, I just had
my first round: making gcc-4.5 + eglibc build with the Binutils gold
linker. There is an issue in gcc/configure[.ac]. I won this time :)
(see <https://github.com/DFE/HidaV/blob/master/meta-hidav/recipes-devtools/gcc/gcc-4.5/gcc-4.5-detect-gold-linker-version-correctly.patch>

Actually we'd like to stay on HEAD and build our own distribution on
top of that. Hence I'm more interested in getting ti81xx-psp-2.6.37 to
work with gcc-4.7. I'll try Martin Jansa's hint
(-mno-unaligned-access) next.

Regards,
Thilo
