eiffel: Create build macros and scripts for the projects

Some Eiffel projects have different processes for builds which require
us to have project specific builder macros and scripts accordingly.

This change introduces such macros and scripts.

In order to ensure reusability, the projects with same build processes
use the same build macro which points to a common build script.

The job name is also updated according to convention.
