Previously we used separate placeholders for builtin linker flags: * CMAKE_<LANG>_LINK_FLAGS for EXECUTABLEs * CMAKE_SHARED_LIBRARY_CREATE_<LANG>_FLAGS for SHARED libraries * CMAKE_SHARED_MODULE_CREATE_<LANG>_FLAGS for MODULE libraries These are now always replaced by the empty string, so drop them from our rule variables.
