Powerpc big endian, fix the expected output file for
none/tests/ppc64/jm_int_isa_2_07.stdout.exp

By convention the file jm_int_isa_2_07.stdout.exp is the big endian reuslts.
If the little endian results differ, the file has -LE appended to it.
This patch replaces the little endian results that are currenttly in
none/tests/ppc64/jm_int_isa_2_07.stdout.exp with the correct the big
endian results.
