I was convinced that there was a missing word or something in 
"because the files that these tools are used to build are included in the
tarball"
I had to read this several times, until I saw that it was actually
correct.

Maybe this would be better? (I don't know the comma rules)
"because the files(,?) that are generated/processed by these tools(,?) are
already included in the tarball"
