Disable stack protection explicitly 

Explicitly disable stack protection via the "-fno-stack-protector"
compiler option when the ENABLE_STACK_PROTECTOR build option is
set to "none" (the default).

This allows the build to complete without link errors on systems where
stack protection is enabled by default in the compiler.
