# Things for make
#   BUILD_OPTS : how to build target files. This is a set of flags:
#		o - Use optimization when building target files (when
#		    applicable)
#		g - Include debugging information
#		p - Include profiling information
#	Multiple flags can be specified in any order, ie. "gop" will
#	enable all options. Note that for some compilers, o and g
#	exclude each other.
#   EXTRA_MAKEFLAGS - The contents of this variable is passed to sub-makes
#   PASSMAKEFLAGS - (internal) This variable contains everything that should
#	always be passed to sub-makes (additional to MAKEFLAGS)
