Summary:                    There doesn't appear to be a cross-platform way to
set flags to be used at compile time but not at link time
Description: 
It appears that if a flag is added to CMAKE_C_FLAGS, it will be used not only at
compile time but also at link time, at least for some platform/compiler
combinations.

Many such flags are, at best, not helpful at link time, and clutter the command
line used for linking.  Some might also not work at link time.

Unix make, and autotools, keep compiler flags (CFLAGS/CXXFLAGS/etc.) and linker
flags (LDFLAGS) separate.  CMake should provide a way to do the same.
