[bitbake-devel] [PATCH 3/6] hob: add a test to ensure hob is run with the required pre and post files

[Joshua Lock]

hob requires pre and post configuration files to store configuration values
in, whilst this should (and will) be fixed long-term for so long as we
require these files we should alert the user should they run without them.

Fixes [YOCTO #1383]
