svn commit: r295820 - projects/mips64-clang/sys/mips/mips

[Sean Bruno]

Author: sbruno
Date: Fri Feb 19 17:32:30 2016
New Revision: 295820
URL: https://svnweb.freebsd.org/changeset/base/295820

Log:
  clang IAS just doesn't handle $at the same way as binutils.  This fixes
  errors and will allow a build of GXEMUL to succeed.
  
  Similar to r295727
