Well, that does seem to be the problem. I don't think the rpath
options got passed down into the configuration.

Here's what I see. (I include objdump from gfortran, f951, and
octave-2.1.73, which I built with the same options. There is no RPATH
set in the gfortran or f951 executables, but it is set in octave.)

I can't tell if this is a bug in the build process or if I'm doing
something wrong. I set LDFLAGS at the very top level, before configure
and make of gcc.
