[PATCH, committed] PR 35148: make pdf and relative srcdir

[Ralf Wildenhues]

Tested `cd gcc && make pdf dvi info html' on i686-pc-linux-gnu, applied
to trunk and gcc-4_2-branch.

I'm actually not quite sure whether I just stepped over approval rules.
The patch has not been posted on this list before, only in the PR,
likewise the approval, see
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35148#c6>.

Also, do I have to add myself to the branch's MAINTAINERS file as well?

Thanks,
Ralf
