[Buildroot] [PATCH v2 4/7] arch/xtensa: accept the overlay to be an URL

[Max Filippov <jcmvbkbc@gmail.com>]

From: "Yann E. MORIN" <yann.morin.1998@free.fr>

It can be interesting to get the overlay from a remote server, rather
than expect it to be present locally.

Since that file can be any URL, we can't know its hash, so we just
exclude it.
