[Lazarus] Getting project type

[Mark Morgan Lloyd]

Does Lazarus (or preferably FPC) define something that can be checked in 
source when it's building a dynamic library (.dll or .so)?

Usage case is that I want to build part of a larger project as a .so, 
and would like to be able to be able to exclude units that aren't 
relevant (so that users see tight binaries when they expect them). I'll 
probably have various -d settings, but would obviously prefer to 
reference standard defines where possible.
