Comment:
Ah, the extras directory and cross compile!

No, it is not necessary and it can be created on the target system after install. It may be possible to create a post install step to do so.

Background: extras contains COBOL sources which are compiled by the generated cobc.

The following options exist to handle that:
* ignore those files (currently there is only one)
* create and install them on the target system manually, if needed
* create and install them via the package manager as post install step on the target system
* have a host version of the same GnuCOBOL version installed and use that to do the compile and link with cross-compile options
