scripts+samples: fix listings the samples

Since we use defconfigs to save the samples, listing all the
samples can no longer be done by passing all the sample names
at one to the script; we need to pass them one-by-one after
we expand the sample's defconfig ibnto a complete .config.

     4 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/53_all_gcc4-superh-default-multilib.patch

     5 The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,

     6 you have to actually list out the multilibs you want or you will end up with

     7 just one when using targets like 'sh4-linux-gnu'.

     8 

     9 The resulting toolchain can't even build a kernel as the kernel needs to build

    10 with the nofpu flag to be sure that no fpu ops are generated.

    11 

    12 Here we restore the gcc-3.x behavior; the additional overhead of building all

    13 of these multilibs by default is negligible.
