I always put my hardware-specific options in /etc/fpc.cfg, so that all
users [of the compiler] on my systems get the right options for local
usage of the compiled applications.  Hopefully, Lazarus does not
override them with any hard-coded values.

If I were shipping compiled binaries, I would take a more "lowest
common denominator" approach, specifying an 80386 or some such.
However, I don't have that problem.
