A first cut at some rules for building elf shared libs. Of particular
note, using "-Wl,-f" to generate a library objects list doesn't work anymore since the hack to ld hasn't been incorporated into binutils-2.8. (and the -f switch is used for something else already) This is disabled by default, don't panic! :-)
