Description: kfreebsd bootstrap necessities
 In the case we use freebsd as OS_TARGET the following goes wrong:
 .
 In fastcgi and fcl-web, something goes wrong with linking:
   ELF interpreter /usr/libexec/ld-elf.so.1 not found
 I have no idea where this comes from as all references to libexec are either
 in fpmake itself after compilation or in t_bsd.pas in parts that should not be
 used. However, if we force it in t_bsd.pas, it at least calls the right linker.
 It still doesn't work though, as the symbols it links to are wrong.
