The native NetBSD ld.so can be built to load SunOS dynamic programs as well.
When put it in /usr/lib (/emul/sunos/usr/lib), SunOS binaries will use it,
giving ample opportunity to search for shared libraries in an entirely
separate set of directories (namely, those mounted/copied from a SunOS system
near you). This can be done relatively easily by the existing LD_LIBRARY_PATH
mechanism by having, say, a LD_LIBRARY_PATH_SUNOS pointing at those directories.
One of the less elegant sides is that such an ld.so must (at the moment) be
linked against SunOS's libc_pic.a library (because it must run in `emul' mode).
