ok then:
        /*
	 * If a binary has a brand, make sure that it is "FreeBSD".
	 * Newer FreeBSD binaries have OSABI set to ELFOSABI_FREEBSD. This
	 * is arguably broken, but they seem to think they need it, for
	 * whatever reason. If the OSABI field is set, insist that it is
	 * ELFOSABI_FREEBSD.

	    strcmp(&eh->e_ident[EI_BRAND], wantBrand) != 0) ||
	    (eh->e_ident[EI_OSABI] != 0 &&
	    eh->e_ident[EI_OSABI] != ELFOSABI_FREEBSD))
		return ENOEXEC;
