[PATCH 2/5] or1k: Add builtin define to detect hard float

[Stafford Horne via Gcc-patches]

This is used in libgcc and now glibc to detect when hardware floating
point operations are supported by the target.

gcc/ChangeLog:

        * config/or1k/or1k.h (TARGET_CPU_CPP_BUILTINS): Add builtin
          define for __or1k_hard_float__.
