Subject: libtool: Avoid relinking when cross compiling, its pointless

There is no point in having "executable" binaries in the .libs
directory linked with different rpaths to the target which
could concivably be run on the build system when cross compiling.

This patch removes the extra rpaths ($compile_rpath) so that the
output from the "link" stage can be used on the target. We can then
avoid having to "relink" during the install stage.

This saves some build time (do_install is over 2 minutes faster for
pulseaudio).

This patch also removes an annoying "seems to be moved" warning
which is totally bogus in the sysroot case.
