This test failure:
math/test-fenv
If rounding mode and exception macros are defined then the fenv tests
run and always fail. This patch adds an ifdef using the
__or1k_hard_float__ macro provided by gcc to avoid defining these fenv
macros when they cnnot be used. This is similar to what is done in csky.
Note, I will post the or1k hard-float support soon. So, I prefer to
leave the hard-float bits here for now.
