Here a fresh clone (parent: 16793:cc1657be1ee7 tip) fails while building 
the parser:

:
/bin/sh ../../octave/build-aux/ylwrap

../../octave/build-aux/ylwrap: line 108: -dv: command not found
make[2]: *** [parse-tree/oct-parse.cc] Error 1


I've experimented a bit but I couldn't spot where the offending "-dv" 
came from.
The isolated "--" comes from libinterp/Makefile (L. 9053).

Any suggestions?
