  Changes in the v8 patch:

1. Redirect target specific roundeven functions for aarch64, ldbl-128ibm
and riscv to fix build for aarch64, power and riscv.  Tested on i686 and
x86-64.  Passed build-many-glibcs.py.  I will checked them in on Friday
if there are no objections.

  math: redirect roundeven function
  x86_64: roundeven with sse4.1 support
  Use GCC builtins for roundeven functions if desired.
