Are you asking for help in compiling your own build, or for someone to compile a build for you?
I am happy to assist with the former, but reluctant to assist with the latter.
Compilation for various platforms is
described in detail in our wiki.
You really should compile yourself if you require a custom build. It is not difficult in any way. Enabling RTC for this target requires absolutely no knowledge of programming whatsoever, and if you learn how to compile your own build you will not be reliant upon others when you find that you want an updated binary.
