Add --disable-new-dtags option when setting rpath
Some newer Linux systems enable the "new dtags" linker option by
default. With this option --rpath sets DT_RUNPATH instead of DT_RPATH.
Unfortunately, DT_RUNPATH is not applied transitively when searching
for indirect dependencies, breaking the Lucy test executable. See
