Log Message:
Remove Linux work-around for bug noted in PR #25402 from arts
and koffice build.

And do in meta-pkgs/kde3/kde3.mk as suggested by maintainer, markd.

It helps with builds on Linux for kdegraphics3, libkipi, gwenview,
kdelibs3, kdebase3, arts, and many other KDE-based packages on Linux.
(It was not needed for kile, but will be used.)

Thank you, Torsten Harenberg for testing many packages such as
kdenetwork, kdegames, kdepim, kdemultimedia.

I still don't know what the correct fix is for PR #25402.
