[kdelibs/frameworks] tier4/kde4support/src: Check for visibility support on gcc

[Aurélien Gâteau]

Git commit 3bc8af3ec4477b5ff7acedd74b27d0d359e8bd1f by Aurélien Gâteau.
Committed on 28/11/2013 at 17:02.
Pushed by gateau into branch 'frameworks'.

Check for visibility support on gcc

__KDE_HAVE_GCC_VISIBILITY was not defined in kdemacros.h.cmake, causing
KDE_EXPORT and KDE_IMPORT to be no-ops, breaking builds of kde-runtime,
kde-workspace and friends.

Don't know what to do for other compilers.
