Err, no - $as_nl_s is set up unconditionally at startup
(_AS_LN_S_PREPARE, called from AS_SHELL_SANITIZE).

Using $ac_ln_s (or $LN_S, or whatever) would break the test, as
those can be overridden by the user; $as_ln_s is always set up to
be the working alternative to 'ln -s'.

Sure, but I figured this was a small enough change (though I did
make a mistake in #1: the .sym wasn't removed from the string literal
in the C code).
