Fix sprintf length warning
One of the supplied argument strings is unneccesarily long (c-sky, using
basically the same code, fixed it to a shorter length) and this fixes overflow
warnings, as GCC fails to deduce that the full 256 bytes for load_op[] are
not used at all.
gcc/ChangeLog:
* config/mcore/mcore.cc (output_inline_const) Make buffer smaller to
silence overflow warnings later on.
