[Qemu-devel] [PATCH] travis: display config.log when configure fails

[Daniel P. Berrangé]

When configure fails in CI systems we must be able to see the contents
of the config.log file to diagnose the root cause.

Makes sense. this fixes the status code of before_script, though previously as
we mask the error with the "|| cat config.log", make will still fail.

If you want one less fork, you can spell this as:

- ./configure ${CONFIG} || { cat config.log && exit 1; }

Either way, the patch makes sense, so:
