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.
