x86_64 is used as a baseline: the "x86_64" entry, whatever status it has,
is transformed into "all", and then the other entries in ARCHITECTURES
either dropped or rearranged appropriately.
* Bump to 2.8.9dev.9 and drop secondary architectures.
* Use relative symlinks (with "ln -sr" instead of "ln -s") when
installing COPYING and COPYHEADER in data/lynx_help/ as symlinks to
the real copies installed in data/lynx_doc/.
* Add USER_SETTINGS_FILES as well as the read-only template config
files, lynx.cfg and lynx.lss, in data/lynx/.
* Edit lynx.cfg to make the STARTFILE variable point to the local
copy of the about_lynx.html document in /system/data/lynx_help/.
* Also in lynx.cfg, edit the definition of the HELPFILE variable to
replace $dataDir/ by /system/data/ as this is required to let lynx
continue to find its help files after the package gets updated.
* Referring the current haiku version explicitly is not needed, since
the RequiresUpdater takes care of setting the version of Haiku used
for building a package.
