Three methods:

1) Do what we do and make the macro definition on the command line:

make FFLAGS="+bfpa" ...

2) or use gnumake and include files.  Gnumake runs on both systems and
   is available via anonymous ftp from prep.ai.mit.edu.

3) or use the make -e flag to have the value of environmental
   variables override the value of variables in the makefile.
