ld: -rpath must search under sysroot

The -rpath argument would search the host filesystem for libraries,
even when a sysroot was defined.  For cross toolchains with targets
compatible with the host architecture this can find incorrect
libraries.  Leave -rpath-link unmodified, as build systems in the wild
are already using this to point to host directories.
