Setting the variables via the shell's environment seems to do the trick. I also renamed my vanilla kernel source litmus-rt.

Is this output fine? It seems to me.

Once liblitmus and Feather-Trace Tools are successfully cross-compiled, by copying  both directories to my rootfs and modifying the path to add the directories:
$ export PATH=$PATH:/liblitmus
$ export PATH=$PATH:/ feather-trace-tools
 I guess I am ready to start playing around with Litmus^RT, right?
