Version-gate appending -syslibroot flag to lld

This commit version-gates appending `-syslibroot` flag to lld. This is predicated upon the fact that for versions of macOS lower than 11, lld would fail to find and link against frameworks with this flag specified. Co-authored-by: Andrew Kelley <andrew@ziglang.org>
