We should not have to maintain the dependency lists of external
libraries (which can even change when the library changes without us
knowing when the API remains the same), especially when a standard
tool exists to handle this for us. pkg-config was specifically
designed for this.
Changes are that such fallback cases are notoriously broken due to any
mainstream system not ever reaching them, so its best to encourage
everyone to use the mainstream option as well.

There is pkg-config for AIX in third-party repos (which is probably
where you get most AIX stuff, since its otherwise a proprietary OS).
