[PATCH] testsuite: Rename test-defined macros

[Dimitar Dimitrov]

Epiphany, PRU, ARC and NDS32 may predefine __big_endian__ and
__little_endian__ macros.  This leads to spurious warnings like:
  gcc.dg/sso/memcpy-1.c:7: warning: "__little_endian__" redefined

Fix by renaming the macros in the test.

Ok for trunk?

gcc/testsuite/ChangeLog:

        * gcc.dg/sso/memcpy-1.c (__big_endian__, __little_endian__):
        Rename macros to avoid conflicts with predefined ones.
