gcc-4.3 will be the first official release that has everything in it,
and I think 4.1 has some parts. However, there are many patched gcc
versions in various distributions, so I tried to avoid being too
specific about the version here.
Of course, on gcc versions that don't support -mtune=cell, the
Kconfig option does not make a difference.
