[kde-freebsd] devel/kdebindings4-smoke: link failure with non-base gcc

[Andriy Gapon]

Environment:
devel/kdebindings4-smoke version 4.4.5
gcc-4.4.5.20100622

Here's how it fails when gcc44 is used for compilation (and CMAKE_VERBOSE is set):

Here's a patch that seems to help.  Not sure if it's proper one.
