New Revision: 231336
URL: http://svn.freebsd.org/changeset/base/231336

Log:
  Implement -print-file-name=include (which is undocumented
  but used by some Linux boot loaders).  This option prints
  out the directory holding the include files needed by
  a freestanding program.  The default implementation of
  this doesn't work on FreeBSD because of the different
  include file layout.  But it's easy to implement:
  just return /usr/include (or the cross-compiling equivalent).
