In order to speed up test bot work it would be helpful to check for identical build outputs and skip tests if required. This removes most use of the install path in c code: - ql_mpi uses /proc/self/exe and looks for talker/server in same directory as itself - mcexec looks for libihk.so in /proc/self/maps and use that path for LD_PRELOAD prefix path - rootfsdir is not used right now but until a better fix happens just hardcode it, someone who wants to change it can set it through cmake There is one last occurence of the install directory, MCEXEC_PATH in mcctrl's binfmt code, for which the build system will just overwrite it to a constant string at build time instead of trying to remove it too hard. It would be possible to pass it as a kernel parameter or look for mcexec in PATH but this is too much work for now. Change-Id: I5d1352bc5748a1ea10dcae4be630f30a07609296
