This is what I found:
# searchpath for units and other system dependent things
-Fu/units/$fpctarget
-Fu/units/$fpctarget/*
-Fu/units/$fpctarget/rtl

It does not really look like a path, at least not a full path.
What should the correct setting be?

I found the system.ppu as follows:

~ $ find /home/pi/ -name system.ppu
/home/pi/lib/fpc/3.0.0/units/arm-linux/rtl/system.ppu

Given that path, what would the correct fpc.cfg setting be?
Something like this perhaps:

-Fu/home/pi/lib/fpc/$fpcversion/units/$fpctarget
-Fu/home/pi/lib/fpc/$fpcversion/units/$fpctarget/*
-Fu/home/pi/lib/fpc/$fpcversion/units/$fpctarget/rtl

I read in a googled article
(http://wiki.freepascal.org/Installing_Lazarus#Installing_from_source)
that one should set these (obviously they are for Windows, but
anyway...):

-FuC:\freepascal\fpc\$FPCVERSION/units/$FPCTARGET/
-FuC:\freepascal\fpc\$FPCVERSION/units/$FPCTARGET/*
-FuC:\freepascal\fpc\$FPCVERSION/units/$FPCTARGET/rtl

Tried to adapt that but to no avail (of course thinking about
sourcefiles then). So this is tested:

-FuC:/home/pi/dev/fpc/$FPCVERSION/rtl/$FPCTARGET/
-FuC:/home/pi/dev/fpc/$FPCVERSION/rtl/$FPCTARGET/*
-FuC:/home/pi/dev/fpc/$FPCVERSION/rtl/$FPCTARGET/rtl
