From: Mariano Lopez <[email protected]>

This will deal with empty lines in DESCRIPTION while creating ipk packages.

From: Mariano Lopez <[email protected]>

opkg uses empty lines as separator for next package and if an ipk file was packaged with empty lines in DESCRIPTION opkg won't be able to handle such ipk file, this happens at execution time.

This commit will replace empty lines in DESCRIPTION with a '.' when generating an ipk package to avoid this issue.

[YOCTO #10677]
