MFC r271365:

  Remove many false positives with make checkdpadd

  - Reduce DPADD and LDADD in checkdpadd to -l<foo>
  - Skip over -Wl,[es]*-group because -Wl,--end-group and
    -Wl,--start-group might be required to properly link objects (see
    usr.bin/clang/lldb as an example)

  This caveat has been present for a while with some components of
  the build. However, these false positives were made more more apparent
  after r269648.
