In some cases we need to specify linker flags and right now we do not have a way to communicate that to cmake based systems. cmake defines CMAKE_C_LINK_FLAGS and CMAKE_CXX_LINK_FLAGS for these needs. This patch therefore defines two local variables namely OECMAKE_C_LINK_FLAGS and OECMAKE_CXX_LINK_FLAGS which can be altered by recipes to tweak linker flags
