This is the OpenRISC port for glibc that I have been working on.

Changes since v2:
 - Fixed suggestions from Joseph Myers:
   - Fix comment style, and description on top of each file
   - Make sure macros have parentheses when needed,
   - Bump required kernel down to 5.4.0 and document
   - Regenerate arch-syscall.h
 - Fixed suggestions from Adhemerval:
   - Remove kernel_stat.h
   - Just set MMAP2_PAGE_UNIT to 8K
   - Remove ioctl.c and syscall.c files
 - Update TCB alignment to 32 bytes

Changes since v1:
 - Update api's as suggested by Florian
 - Remove hard float support
 - Updates to get all tests passing
 - Split patch into managable bits similar to recent ARC port

Documentation:

  Architecture / ABI docs:
   https://raw.githubusercontent.com/openrisc/doc/master/openrisc-arch-1.3-rev1.pdf

Test Results:

  build-many-glibcs.py:

   PASS with mainline ang gcc-11.

  Full test suite:

   The full suite is running using the gcc-11 branch of GCC, mainline shows
   issues with math soft-fp.

   Note, there are a few more failures compared to before, this is due to me
   running with a timeout of 30 vs usual 300.  It allows the tests to complete
   faster, but I get a few more timeouts.  There were 15 timeouts which I
   confirm do work if I increase the timeoutfactor. The 2 real failures marked
   with * below.
