- add many subdirs of libs missing
- output a literal $NetBSD$ as well as the expanded version of this script
- special case a bunch of the external subdirs, since some of the library
subdirs exist in toplevel directory, not the "lib" directory
two issues remain:
- LIBDPLIBS isn't working correctly, requiring hand-holding builds
- libc, libipsec, and libpcap have yacc issues, also requiring hand holding
ideally this will be replaced with a better method that can handle more
than one compat target, but i can't get that working yet. see the README
file for mroe details.
