The simplest way would be to change the ELF OSABI that the kernel
loader recognises as FreeBSD (patch ELFOSABI_FREEBSD in
sys/sys/elf_common.h and rebuild).  You would need to use brandelf to
patch executables built on other FreeBSD systems.

There's a set of patches implementing mac_chkexec floating around
see (eg) http://lists.virus.org/freebsd-security-0503/msg00042.html
This might do what you want.
