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

[Stafford Horne <shorne@gmail.com>]

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__.
