More needs to be done to make it more compact, i.e. elide the '-f Makefile',
remove that 'cd . &&', move the DESTDIR= and O= to the end, as they don't
convey that much information besides the fact that they are being set to some
random directory just for this build, move the meat, i.e. the meaningful
feature disabling bits to the start, etc.
