This series adds hardware floating point support to the OpenRIS glibc port.

I will keep this cover letter short and point to patch 2/3.  It contains details
about the change and testing results.

Changes since v2:

 - Remove spurious whitespace cleanup.
 - Add a bit more docs and explaination about the FPSCR register flags.
 - Add Reviewed-by from Adhemerval.

Changes since v1:

 - Added combat symbols for getcontext, setcontext etc. Supporting old
   mcontext_t ABI.
 - Split fpu ulps file out to separate patch to make the main patch smaller.

Stafford Horne (3):
  or1k: Add hard float libm-test-ulps
  or1k: Add hard float support
  build-many-glibcs.py: Add openrisc hard float glibc variant
