    arm: remove error in CPP_SPEC when -mlittle-endian and -mbig-endian are used together
    
    arm.h has had this error message since 1997, but it is no longer
    needed since option parsing has been improved: -mXXX-endian is handled
    via arm.opt and updates the BIG_END mask. So, the last
    instance of -mXXX-endian on the command line wins.
    
    Tested on many arm* configurations, with no impact on the testsuite results.

            -mlittle-endian/-mbig-endian conflict.
