In hybrid mode, all programs are dynamic executables and ld.lib.so is
not supported. Therefore, only the "static" variant of the test can be
build and executed.
Revised region management detects region conflicts by using _soft_
mappings per default. Overmapping is activated for population of managed
dataspaces only. For more information see header documentation of
base-linux/src/base/env/rm_session_mmap.cc.
Fixes#883.
