Current code tests treats "" (quotes included) as an empty value for that varible (as coming from Kconfig). However, that file also used to integrate with build systems for 3rd-party components, e.g. as examplified by samples/static_lib, and in that case it will be just an empty string. So, first strip surrounding quotes, then test for empty string. samples/static_lib: Update for recent Makefile.toolchain.zephyr changes. Makefile.toolchain.zephyr is 2-pass now, so needs to be included twice. ARCH needs to be defined *before* including it. Otherwise, just used CROSS_COMPILE and TOOLCHAIN_CFLAGS set by it.
