I think it's not a good idea to embed ${PREFIX} and ${PREFIX}/cross
into the binary. I would install to "/usr/local", but with ${DESTDIR}
set to "${PREFIX}/emul/linux", so it will *install* to
"${PREFIX}/emul/linux/usr/local", but the program will think it's
in "/usr/local", just as a native linux binary does. You shouldn't
have to tell the build system about "${PREFIX}/cross, either;
the cross compiler should do that transparently.

The ".so" files in ".../cross" are for use by the linker. You don't really
want a run-time dependency upon anything in cross. The run-time dependency
should be on the base linux libraries: the linux run-time interpreter will
think to find "ld-linux.so.2" in "/lib", but the kernel emulation and
symlinks will conspire to present it "/usr/pkg/emul/linux/lib" (again,
just like a pre-built native linux binary).

In any case...

linux binaries don't really need RPATH. You can just set ${CHECK_SHLIBS}
to "NO" in the package "Makefile" to avoid the error.
