[CMake] Supplying different debug flags during compile and link stages for libraries and executables

[Petr Kmoch]

Hi Brett,

as far as I know, compilation flags come from
CMAKE_<lang>_FLAGS_<config>, while linker flags come from
CMAKE_{SHARED|EXE}_LINKER_FLAGS[_<config>]. So you should be able to
override CMAKE_SHARED_LINKER_FLAGS_Debug (not sure with correct case
for configuration name) and remove -g from there.
