Yes.

CMake links a test executable but never runs it.  It parses information
right out of the binary.

If the toolchain can't create executables then this information needs
to be set in the toolchain file.  This is the purpose of the
CMAKE_C_COMPILER_FORCED setting: tell CMake that the toolchain file
takes care of this information.
