Details:

When `make' is called on multiple threads, sometimes the `git shortlog'
command in `doc/genauthors' doesn't make any output. Therefore `authors.texi'
remains empty. 

In commit c5b6cee (Check added to see if doc/authors.texi is empty) a test was
added to check if `doc/authors.texi' is empty. If so, `doc/genauthors' exits
with a non-zero value (failure). So the building process stops and the
user/developer is informed. By running a simple `make' it will be built, and
since the documentation is the last part to be built, there won't be any
problem with building the libraries and utilities.

However, this is not an elegant solution! We have to find a solution, so `git
shortlog' makes an output everytime `make -jN' is run, not randomly.
