Added new support for NT and AIX dynamic linking - generate export tables
for executable files, not just libraries/modules. Also, the AIX linker hardcodes -L paths by default; override this to prevent build paths from appearing in distributed binaries. mkdep.aix - a wrapper for AIX cc that sends dependency info to stdout so that the standard mkdep script can operate.
