x86_64 Illegal FPU type

Are there compiler options equivalent to {$FPUTYPE SSE2}{$I-} that would allow the same program to be compiled for different hardware without source code changes?

FPUTYPE is a cpu specific switch. You can either write
{$ifdef cpui386}{$FPUTYPE SSE2}{$endif cpui386}{$I-}

or only

{$I-}

and pass the FPU type with -Cfsse2 at the command line.
