Doc test linking failure if there are native dependencies

[vhbit]

TL;DR while building doc tests -L$(NATIVE_DEPS_DIR) isn't added to flags and therefore linking fails.

You can test it on this

Here is output:

Here is output of build command:

Forcing static linking solved the issue, so it seems to be my configuration mistake rather than Cargo error.
