Thanks!
This seem to correctly run record and replay command lines.
When I break the replay correctness, then the test reports a timeout error.
However, we need some kind of a manual for tcg testing. I had to dig through
makefile and configure
scripts to undestand that testing needs the cross compilers to be installed.
Then I installed a random cross compiler and everything worked normally.
