New Revision: 276128
URL: https://svnweb.freebsd.org/changeset/base/276128

Log:
  Fix build with recent binutils
  
  Recent binutils considered the .gnu.warning.symbol section as a fatal error when
  run with --fatal-warnings which makes any users of "insecure" functions from
  libc failing to build with recent binutils.
  
  Introduce a new macro: LD_FATAL_WARNINGS=no to run ld(1) with
  --no-fatal-warnings for the users of "insecure" functions
