I suppose that we need

Huh? I did apply the two patches and I do have tools/ltx/Makefile

And actually there is a minor problem there, without the submodules
checked out I get:

CC ltx
gcc: fatal error: no input files
compilation terminated.
make: *** [Makefile:21: ltx] Error 1

So I guess that we need:

diff --git a/tools/ltx/Makefile b/tools/ltx/Makefile

Because if there is a directory with the name ltx it horribly confused
Make.

I'm not sure that we can do things simpler, the Makefile in the ltx git
repository does not support out of tree build, so unless we remove that
from LTP this is probably the easiest solution.

It is there.
