Remove OSSILE dependency and build with make

[worksofliam]

I am not expecting this to get merged, but this PR includes the following changes:

• Removes the OSSILE dependency and builds MESSAGES & ARRAYLIST as part of the build. (Remove dependency on OSSILE #4 )
• Includes makefile to replace build shell script. The makefile can build both the application and tests. (Create a build script #5)
• The RPG sources are now built from the IFS.

Thanks!
Liam

Liam,
Can you break this out? Removing the dependency and adding the make file separate?
Also two other notes, we would like to leave the build file as an option and we support all the way back to v7r1. I noticed the make file only went back to v7r2.
Thank you for your help!
Marina

Hi @MarinaSchwenk

make would allow you to build back to 7.1, but 7.2 is the default (as you saw).

gmake would build with 7.2 as the target.
gmake TARGET=V7R1M0 would build with 7.1 as the target.
