CMakeLists: remove fixed options for NONE

The use of the NONE toolchain option is such that we can provide at the
build project level (buildroot etc...). However, the changes introduced
in 811f2b5 set certain compiler/linker
option that does not comply with the definition of the options as
specified in [1]. This change removes those options.
