svn commit: r202957 - in projects/ppc64: lib/libc/gen sys/sys

[Nathan Whitehorn]

Author: nwhitehorn

New Revision: 202957
URL: http://svn.freebsd.org/changeset/base/202957

Log:
  Tweak the weak_reference definition some more. Only text symbols require
  additional definition of a weak linkage for the dot symbols, so provide
  a new weak_reference_data for data symbols.
