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.

     2  The generated libtool for building libstdc++ adds the -nostdlib option to the
     3  g++ command for linking but doesn't add -lgcc.  This causes a "hidden symbol"
     4  error when linking against the libstdc++ shared object.  This patch adds gcc
     5  to the list of libraries linked against when linking libstdc++.
