New Revision: 244906
URL: http://svnweb.freebsd.org/changeset/base/244906

Log:
  MFC r244600:
  
  Fix a bug in ld --gc-sections: it strips out .note sections, while it
  should never do so.  This can cause global constructors and destructors
  to not be executed at run-time, resulting in crashes and other strange
  behaviour.
