Should fix PR19526.
When Oscar added this code in the intial CMake build system port, he had
a TODO saying that ${CMAKE_SHARED_LINKER_FLAGS} was probably wrong. I
agree. I'm using ${CMAKE_CXX_LINK_FLAGS} to point LLVM at my custom
installation of gcc 4.recent, so that seems more correct. With this
change, I can build creduce against an installed clang, and it picks up
the write flags from --ldflags.
