mconf-idf: Use same 'simple expand' logic, same as kconfig-frontends Previously, wordexp() was used. However for providing Windows builds of mconf-idf we can't use wordexp() so we use this simplified environment variable expansion code instead. The reasoning here is to make the behaviour consistent across Windows (CMake vs GNU Make), Linux & macOS mconf. 2019-06-27 23:35:55 -04:00			`#pragma once`
