Currently texlive does not build on ppc64le due to building an embedded
luajit from inside the texlive package.
This luajit source does not contain ppc64le bits, thus, it FTBFS.
Ideally, we would like to use system lua and luajit, but, the luajit
build is instrinsics to current texlive building process. In this case,
I am just removing luajittex on ppc64le.
