samples: rework show-tuple

Now that we are using defconfig files, the samples do not contain
the full configuration, so we can not simply parse them to show
their content.

Instead, we must fake recalling a sample, and parse the generated
.config file.

     1 The m68k mcpu processor does not like unaligned access
     2 
     3 Disable at least mcpu32, m68010 and m68020. These processors certainly
     4 do not like unaligned accesses.
