I'm not entirely sure this *has* to be given via CMAKE_EXE_LINKER_FLAGS, but this would have stopped at least one person from trying. Static linking 1. does not work at the moment, 2. is not *useful*. You don't get a single-file fish you can just copy somewhere because you're missing our functions. On glibc systems you also can't statically link glibc. Given all that, it does not appear to be worth putting in any effort to make it work (if it's possible at all). See #7947.
