Arch Linux

Description:
When running db2html script on Arch, it generates output in the current directory. This behaviour is different from db2html provided by other distributions, which creates a directory and puts all output files under the directory. This causes gtk2 to fail to build when docbook-utils is installed because the Makefile can't find the output directory.

This problem was reported by an AUR user on mingw-w64-gtk2 package (https://aur.archlinux.org/packages/mingw-w64-gtk2/#comment-762651).

Additional info:
* docbook-utils 0.6.14-10

Steps to reproduce:
1. Install docbook-utils.
2. Build gtk2 and see it fails.

if test -w .; then \
(cd .; \
db2html gtk-tut.sgml; \
test -d html && rm -r html; \

mkdir html/images; \
cp images/*.png html/images); \

On Arch Linux, db2html is a symlink to docbook2html:

On other distributions, db2html is a script different from docbook2html.

If I replace the db2html script by the one provided by Fedora (https://src.fedoraproject.org/rpms/docbook-utils/blob/b6ea8c1a3808be8a870273608323b4582c657dbd/f/db2html), gtk2 can be successfully built.
