support/download: add possibility to not fail on missing hash
In very constrained cases, it might be needed to not fail if a hash is
missing. This is notably the case for custom external toolchains to be
downloaded, because we do have a .hash file for external toolchains,
but we obviously can not have hashes for all existing custom toolchains
(he, "custom"!).
So, add a way to avoid failing in that case.
>From the Makefile, we export the list of files for which not to check
the hash. Then, from the check-hash script, if no check was done, and
the file we were trying to match in in this exclusion list, we just exit
without error.
