[Bug other/36779] New: make pdf fails if done before another make

["hal at oz dot net" <gcc-bugzilla at gcc dot gnu dot org>]

This is pretty trivial, but it would be nice to fix.

I tried to generate the pdf documents for gcc 4.3.1 on an x86 running fedora 9
without building gcc first.  I ran configure with no options (in a separate
directory from the gcc source tree), then "make pdf".  It generated a lot of
the pdf documents, but then quit in one of the subdirectories because
./gcc/xgcc didn't exist.  Here's the tail end of the console output:
