svn commit: r352032 - in head/stand: . i386/loader

New Revision: 352032
URL: https://svnweb.freebsd.org/changeset/base/352032

Log:
  loader: --gc-sections needs sections to work with
  
  --gc-sections is not really useful unless we generate sections with
  -ffunction-sections -fdata-sections
  
  While there, i386/loader would win from --gc-sections too.
