Although it is a welcome feature, it will make the usage really 
complicated considering build modes might cater for debug/release, FPC 
version, win/linux, etc...

I instead propose to have a field next to the compiler path in the IDE 
options that accepts fpc's -Xp parameter. Xp allows one to specify the 
relative folder of the actual compiler (ppcxxx) with respect to the fpc 
executable. That would work well since each ppcxxx's location is fixed 
with respect to its associated fpc executable.
