[fpc-pascal] FPC to create PHP extensions for Linux

After a night of dwelling on the problem, the easiest solution is to create
your linux dynamic libraries as a standalone separate lib.so library in 
free pascal
and then use C to create the php extension and link it to the freepascal 

Trying to keep up with all of the PHP headers is a real pain in the ass 
so just
use the extension environment to wrap the Pascal library is the best way.

This is identical to the mysqli interface where the extension links in 
the libmysqlclient.so.xx library
into the php binary.

Hope this helps anyone doing this sort of thing.
