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

Changes since v3:
 - Fix suggestion from Paul Eggert
   - Fix Docs typo pore/port
 - Fixed suggestions from Adhemerval:
   - Used ENTRY/END asm macros where missing
   - Remove block in dl-machine.h suggesting LD_PROFILE
   - Remove jmp_buf-macros.h  macros and use new default.
   - Remove tcb-offsets.sym file and Makefile reference.
   - Remove tcb-offsets.h include in tls.h.
   - Define lib-audit register layout inline with other architectures.
   - Fix usage of locally defined register in or1k_get_got.  Also, fixup
     indentation when using or1k_get_got.
   - Cleanup abilists after rebasing, adding rseq and removing
     empty files.
   - Remove prctl and other unused entries in the linux Makefile.
   - Fix STACK_ALIGN to 4 bytes, from incorrect copy-n-paste 16 bytes.
   - Use default pthreadtypes-arch.h.
   - Mention only soft-float supported in NEWS.
   - Remove sysdeps/unix/sysv/linux/or1k/bits/timesize.h and use new
     default.

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

  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:

  This time I ran the test suite with timeout of 300 and with patch for forcing
  O_LARGEFILE in open64 [0].  The test has one failure but it seems like flaky
  test as it passed after the second run.

The port seems to be in good shape I would recommend to send just another versions
with the nits and fixes me an Joseph raised:

  - Use Elf32_Addr and Elf32_Sym on link.h and sotruss-lib.c.
  - Check if the inline assembly dl-machine.h requires the 'memory' clobber.
  - Remove the superflous atomic typedefs on atomic-machine.h.
  - Add the _dl_find_object on libc.abilist.
  - Remove libnsl.abilist.
  - Maybe use the current wording for the NEWS entry.

I think with a v5 with the above fixed we can push it for 2.35.
