[PATCH] meson.build: make special_funcs check more reliable

Unfortunately while cross-compiling with build tools like Buildroot it
happens to have repeated flags or anything that could lead to a warning.
This way the check fails because of a warning not related to the special
function. So let's use cc.links() and increase minimum meson_version to
0.60 since cc.links() has been added during that version.
