build system: Use component.mk for all components, refactor bootloader build For config-only components, component.mk should now contain "COMPONENT_CONFIG_ONLY := 1" Also refactored some of the generation of linker paths, library list. This required cleaning up the way the bootloader project works, it's now mostly independent from the parent. 2017-06-23 14:08:01 +10:00			`COMPONENT_ADD_LDFLAGS += -u __cxa_guard_dummy`
