exim - external DB lookups support not working

[willdeane]

The Exim Makefile includes support for a number of external lookups but they aren't making into the final binary, I'm specifically looking for postgreql support.

The command exim -bV provides details of the supported features

Based on the Makefile config if it was building correctly I'd expect the lookup support to include
