New Revision: 197277
URL: http://svn.freebsd.org/changeset/base/197277

Log:
  Make libc.a provide __stack_chk_fail_local weak alias. This is
  needed to satisfy static libraries that are compiled with -fpic
  and linked into static binary afterwards. Several libraries in
  gcc are examples of such static libs.
