An ifdef is a different beast from a {$i }. Defines are set on the cmdline
(e.g. -dLCLGTK2 in the above case), while $I are 

either built in (FPCVERSION, DATE, the easiest is to look up the
{$i %..%} syntax in the manual for a list)

_or_ an environmentvariable. This can be used to pass content like this, but
means that lazarus has to set them in the environment that FPC calls.

The advantage of this, is that it will work with any 2.x FPC version.

FPC doesn't know anything about LCL or Lazarus, let alone its exact
versioning.  But it can regurgitate information it gets passed _by_ Lazarus. 
Defines and {$I %environmentvariable%} are examples of this.
