Optionally exclude implicit link directories via environment
A misconfigured compiler may pass extraneous implicit link directories
to its linker. If they are in `CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES`,
CMake may generate extra `-L` flags on mixed-language link lines that
break linking. Add an environment variable that users can set to work
around such misconfiguration of their compilers.
