crossgcc: update to gcc 4.7.3

Update crossgcc to use gcc 4.7.3
The resulting coreboot.rom is not runtime tested (any volunteers?).

Drop the texinfo patch, rename the armv7a patch.

Some Linux distributions have moved on to gcc 4.8,
under certain circumstances this version can't (cross-)compile gcc 4.7.2
