And -R is a non-standard command line option for compilers.  Turns out
that they both work in pretty much the same places and don't work in
pretty much the same places.

LD_RUN_PATH is overridden by -R on the command line.  Other than that, no,
there's no difference.  LD_RUN_PATH is what we use internally here at
Stanford to build software since it's less intrusive in the build process
and also works with software that doesn't use Autoconf (whereas LDFLAGS
may or may not).

The only way to really get this right on a cross-platform basis is to use
libtool.
