Checking the commit history again, "-lc" was added with FindKDE4.cmake
itself in r497823 [1], apparently when porting the autotools code to
CMake.

The flag was added to kde-common/admin/libtool.m4.in in r141814 [2] with
a libtool update, and as of KDE 3.5.10 (if my reading is correct) "-lc"
was passed only on AIX.

I guess we're good to go here.
