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.

* config/arm/arm.h (CPP_SPEC): Remove error message about
-mlittle-endian/-mbig-endian conflict.
