svn commit: r286791 - in head: share/mk usr.bin/lorder

New Revision: 286791
URL: https://svnweb.freebsd.org/changeset/base/286791

Log:
  Introduce a new make variable: NMFLAGS.
  
  As the name indicates, these are flags to pass to nm(1).  The newer
  binutils have a plugin mechanism so, to build something with LLVM's
  LTO, we need to pass flags to nm(1).  This commit also extends
  lorder(1) to pass NMFLAGS to nm(1).
