BUILD: makefile: build the features list dynamically

Browse Source 
The BUILD_FEATURES string was created too early to inherit implicit
additions. This could make the features list report that some features
were disabled while they had later been enabled. Better make it a macro
that is interpreted where needed based on the current state of each
option.
