You can tell Lazarus which binary to use for FPC.

For the config file, you can use the same for all. The ~/.fpg.cfg is 
just a text file containing parameters to give to the compiler, same as 
the command like, but with some additional preprocessing. You can use 
something like

#IFDEF VER<FPC version>
parameters just for that FPC
#ENDIF

But note that the default configuration should work fine with most FPCs 
as long as they are installed in the same prefix since they use 
$fpcversion and $fpctarget macros instead of hardcoding things. For 
example personally i have both stable and git versions of FPC installed 
in ~/Apps/fpc for various targets and each uses its own set of units, etc.

If you have FPCs placed in different prefixes you might need the IFDEF 
for those though - or perhaps just add directories for both prefixes and 
as long as the $fpcversion macro is used for the units it'll work.
