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