newlib: add "full" formatting support, add missing functions - add two versions of libc: libc.a and libc_nano.a. First one has full C99 formatting support, second one uses “nano” formatting functions available in ROM. - fix linker error for fmod, fmodf, atof, atoff - update tests 2016-11-07 05:43:29 -05:00			`ifeq ("$(CONFIG_NEWLIB_NANO_FORMAT)","y")`

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 00:08:01 -04:00			`COMPONENT_ADD_LDFLAGS += $(COMPONENT_PATH)/libhal.a \`

build system: Refactor SubmoduleCheck to work project-wide Required at project level because some components use header files in other components' submodules, and one component with a submodule (esptool.py) doesn't have or need a component.mk. 2016-11-15 19:12:48 -05:00			`COMPONENT_SUBMODULES += lib`
