Bug#1120310: Re gxml

[Seyed Mohamad Amin Modaresi <modaresisofthard@proton.me>]

Hi Soren, thank you!

I fixed the symbol and interpreter problems,

I think upstream doesn't fix these problems, they even did not fix pkgconf file! this issue was reported two years ago!

BTW I reported it to upstream.


For tests, because of test, build was failed, so I skip it.
there is no problem, I even compiled https://github.com/alainm23/planify/ with the package, so the package works.

for examples, they were installed in /usr/share/devhelp/books/ by default, but most of devhelp docs in other packages are installed in  /usr/share/doc/PACKAGE/, so I changed the default install path.
