Introducing OpenCOBOL

OpenCOBOL is an open source COBOL compiler.
OpenCOBOL implements a substantial part of the COBOL 85 and COBOL 2002 standards, as well as many extensions of the existent COBOL compilers.
Removed unnecessary environment flags, referenced bug report for option in configure script.
Use libiconv from OS X
Use OS X gettext for build, no optional dependency
Add test compiling hello world program using cobc

The test checks if a hello world program is successfully compiled
and could be executed afterwards.
Removed cobc-config from test run
Use #{info} instead of specifying path
