[erlang-bugs] Building docs for R13B-03 fails

I did some further investigations and found that simply calling make
in all doc/src
directories works better then trying to run make recursively.

for i in `find . -wholename '*/doc/src'` ; do
    (cd $i ; make man ERL_TOP=$pwd )

(using Erlang R12B-02-1 edoc and docbuilder, and the attached docb_gen script)
generates manpages perfectly, make html and make pdf though suffer from runtime
errors while running xsltproc.

Running make recursively reveals a whole bunch of problems with
missing and redefined
'docs' targets in makefiles.
