[GSoC 2020: Daily Update]: Building EPICS with RTEMS5

[Mritunjay Sharma]

Hello everyone,

Thank you, Heinz, Gedare, Chris and Joel for your advice.
If there are issues in making a buildset for 4.10
then should I build EPICS with RTEMS 5 by hand first and note
down the process and then proceed to make the buildset for it?

Please suggest for the future steps.

Thanks
Mritunjay
