m68k: disable BR2_BINFMT_FLAT_SEP_DATA for coldfire
BR2_BINFMT_FLAT_SEP_DATA can be used to create XIP userland and works fine
for m68k. Unfortunately a lot of basic packages as pcre are not compileable
because of a CPU or hardware limitation. The reason for failing are very
big functions used in the libraries or application code.
Typical errors are:
Fatal error: Tried to convert PC relative branch to absolute jump
or
error: value -yyyyy out of range
Add kernel patch from 4ec5542679264bc06a0356ef92f06ad7a0abe06d to make
BR2_BINFMT_FLAT_ONE compiled firmware work fine.

[Thomas: add comment in Config.in file about sep-data existing on m68k,
but being disabled due to build issues with numerous packages.]
