I haven't tried gcc-4.7 on my armv4t machines yet, because I fear
similar issues like with binutils gold (which are still not resolved),
because nobody uses armv4t much nowadays :/.

The same I fear from 4.6 from meta-linaro, but maybe they will be
responsive as you were, when I reported issues on armv4t with some new
patch added by linaro..

So using meta-linaro for gcc-4.6 and gcc-4.7 is fine, but please keep
current "snapshot" of gcc-4.6 (oe-core+toolchain-layer patches)
somewhere as safe version before meta-linaro 4.6 is well tested on all
devices.

Cheers,
