--- Comment #4 from John Marino <gnugcc at marino dot st> ---
I suspect the reason it works on FreeBSD is found on libgcc/config.host,
specifically the inclusion of t-freebsd in tmake_file definition.

t-freebsd for i386 add the symbol map $(srcdir)/config/i386/libgcc-bsd.ver
which defines __cpu_model for gcc48 and higher.

DragonFly probably needs the same symbol map.
