On startup, the compiler looks for fpc.cfg in $PPC_CONFIG_PATH. This  
is documented in the manual: http://www.freepascal.org/docs-html/user/userse6.html

And actually, there you can see that there is another variable that  
may be useful to you: FPCDIR. Its functionality has not been  
maintained in the compiler though. If it is set, then
a) if $FPCDIR/rtl exists, the compiler will also look for units in  
$FPCDIR/rtl/$FPCTARGET
b) if $FPCDIR/rtl does not exist but if $FPCDIR/units exists, then the  
compiler will also look for units in $FPCDIR/units/$FPCTARGET

It will not look in subdirectories of that directory, so this  
functionality not really useful anymore.
