I have 2 fpc.cfg files and the one in /etc is from year 2017 so I think 
that one only applies to Laz 32.   The other fpc.cfg is in ~/ 
Development/FreePascal/fpc/bin/x86_64-darwin/fpc.cfg and is from October 
18th 2019.   So inspecting this second file I find:

#ifndef cpupowerpc64
-XR/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk

#ifdef cpui386
-Fl/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib

# searchpath for libraries
#-Fl/Users/danstar/Development/FreePascal/fpc/lib
#-Fl/lib;/usr/lib
-Fl/Users/danstar/Development/FreePascal/fpc/lib/$FPCTARGET

# library search path
-Fl/usr/lib/$FPCTARGET;/usr/lib/$FPCTARGET-gnu;/lib/$FPCTARGET;/lib/$FPCTARGET-gnu;/usr/lib/gcc/

And my reading of this is -Fl only applies to PowerPC cpu hardware.   So 
I am confused what to change.  Any help appreciated.
