Make:Use environment variables for OS detection.
Add make helper files to select the appropriate settings for the build environment. Selection is made in make_helpers/build_env.mk, which selects other files to include using generic build environment settings. The Trusted Firmware Makefile and supporting tool Makefiles are updated to include build_env.mk instead of unix.mk. NOTE: This change does not fully enable builds in other build environments. It facilitates this without compromising the existing build environments. Change-Id: Ic4064ffe6ce158bbd16d7cc9f27dd4655a3580f6
