Sorry for the late. Actually I just tested with commit a02e947 ("lib: add linker tables test driver")
on branch mcgrof-next/20170113-linker-tables-v7-try2, and the warning log persists.
See dmesg attached.

Nice suggestion. Actually we've added '-N' option for wget which will record file's timestamp,
and it will only re-download if remote file is newer than the local one. However, github server
seems refuse to send timestamp as wget would get message 'Last-modified header missing -- time-stamps
turned off', thus wget will ignore timestamp and re-download every time.
One workaround is to replace '-N' with '-nc' which means skip downloads if file exists.

The risk is that it doesn't check the timestamp, so once you have a local cached file and we update the
remote one on github, `lkp qemu` would alway use the old one , but I figure it doesn't matter for this case.
