cmake: Error out with "-static"

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.
