CMAKE_LINKER is used only in some rare cases, I think it was e.g. when 
building for eCos, an embedded RTOS, where you link the executable with a 
whole lot of special arguments for ld, and maybe for some other embedded 
stuff.
Nevertheless it exists as a generic variable in all cases so that in case you 
want to invoke the linker to do something, or cmake later on wants to do 
something with it (...like maybe something with static and shared libs), then 
it is already there.
