That seems unlikely to work.  If you want to be able to run programs on 
a freebsd system, you should use the freebsd libraries and header files. 
  There is a --with-sysroot configure option that can help here.  Copy 
the  /usr/include and /usr/lib directories from the target system to the 
host, and then point gcc to the freebsd root directory with --with-sysroot.

See the STARTFILE_SPEC definition in i386/freebsd.h.  The default 
definition in gcc.c uses crt0.o.  The freebsd one uses crt1.o.
