Build Environment Effort/Zen of gbuild

Zen of gbuild
- One use make process, do not recurse.
 - Always have good dependencies and good clean targets.
 - Have exactly one $(OUTDIR) target per declaration file.
 - Use only tools as defined by POSIX:2008 and supported on all platforms. Exception: GNU extensions are allowed for cp, make, tar and touch.
 - Use only POSIX sh, POSIX awk, C/C++ and GNU make in gbuild core.
 - Otherwise, put the file in the extensions subdirectory and do not depend the core functionality on it.
 - Use the gb_Output_* functions for notifications.
 - Keep all platform specific stuff confined in the platform subdirectory of gbuild.
 - Never use relative paths, only absolute paths starting with $(OUTDIR), $(WORKDIR) and the repository roots (for example $(SRCDIR)) should be used.
 - Adhere to the Zen of Python, for it is valid in any language.
