[Buildroot] [PATCH 5/7 v3] support/download: properly catch missing hashes

Sun Mar 22 15:21:04 UTC 2015
When checking hashes reports no hash for a file, and this is treated as
an error (now: because BR2_ENFORCE_CHECK_HASH is set; later: because
that will be the new and only behaviour), exit promptly in error.
