Makefile.inc: Mark stack as not executable

Suppress the warning:
    missing .note.GNU-stack section implies executable stack
    NOTE: This behaviour is deprecated and will be removed in a
    future version of the linker

Since we don't need an executable stack this is fine. Some newer
linkers like LLD even default to this.
