It is a fork issue and you need to use

rebaseall -T file_list

if you want to rebase also the just build dlls.
Rebase has no knowledge of them

find /home/danilo.zanatta/octave-dev/oct_build -name "*.dll" > file_list

However the dlls just build are VERY large and a fork issue is
still possible. An alternative solution is

make install-strip
(it will fail at the same point, no problem)

find /usr/local -name "*.dll" > file_list
find /usr/local -name "*.oct" >> file_list

(from dash)
rebaseall -T file_list

cd /home/danilo.zanatta/octave-dev/oct_build/doc/interpreter
sed -e "s/\$(top_builddir)\/run-octave/octave-cli/" Makefile > Makefile_doc

make -f Makefile_doc
(so to build all the images you use the just installed stripped dll's 
that are smaller)

cd /home/danilo.zanatta/octave-dev/oct_build
make
(the build should complete now)
