build: time for efl-one

this is building parts of efl into a single .so and links all modules
and binaries to it.

The libraries themselfs are build as .a's which are linked together as
.so's. Which is required as every subproject has its little custom
c_flags, which are somtimes conflicting.

After the final .so is then built, all the split up libraries are
replaced with the efl-one. After that the modules and binaries are built
correctly with the correct link on the efl-one parts.
