Jörg Thalheim 82caa0683d [Scripts] Make bash shebangs portable
Unlike /usr/bin/env which is a Posix standard, there is no guarentee
that /bin/bash exists. This is the case for operating systems such
as FreeBSD, NixOS and Guix. By using /usr/bin/env we also give
the user the option to provide their own bash in a different path
by setting the $PATH environemnt variable.
Distributions usually provide their own packaging wrappers
to fixup shebangs upon installation, however those are not convienent
to use when developing in the source tree.

Simon Gaiser 9052837dfc [Make] Improve download handling
Instead of implementing downloading of external resources in every
Makefile again, use one script. This script adds the following
features:

 - Always check the download against a known SHA-256 hash.

 - Support caching of downloaded resources (set DL_CACHE=/some/dir).

 - Allow offline builds if all files are cached. If DL_OFFLINE=true the
   build will never attempt to download anything.
