[bitbake-devel] [PATCH] cookerdata.py: check for existence of configuration files

[Juro Bystricky]

Presently there is no check to verify the existence of configuration
files as listed in BBMULTICONFIG. For example, BBMULTICONFIG = "foobar" in local.conf
does not trigger an error when there is no conf/multiconfig/foobar.conf.
The missing file is silently ignored.

This patch verifies the existence of config files and errors-out with the message:

ERROR: BBMULTICONFIG="foobar" but the configuration file './conf/multiconfig/foobar.conf' does not exist!

when the file does not exist.
