Code review comment for lp://qastaging/~tplavcic/percona-xtrabackup/bug1156209-2.2

Yep, you're right.
Seems the problem was in badly defined outputs and dependencies for latexpdf target since it depends on the output of latex target - it needs Makefile which is produced there and tex file also - when parallel building was done it only looked for existance of doc/source/build/latex directory but final and needed outputs maybe were not created yet - at least that is my current understanding.

So I managed to reproduce your error and with this new commit I cannot reproduce it so please check.

Here's jenkins jobs with some testing:
