The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,
yann@1162
     6
you have to actually list out the multilibs you want or you will end up with
yann@1162
     7
just one when using targets like 'sh4-linux-gnu'.

The resulting toolchain can't even build a kernel as the kernel needs to build
yann@1162
    10
with the nofpu flag to be sure that no fpu ops are generated.

Here we restore the gcc-3.x behavior; the additional overhead of building all
yann@1162
    13
of these multilibs by default is negligible.
