Because make does not (yet) pass make variables to $(shell) subshells.

Try this:

  $ make -f debian/rules DEB_BUILD_OPTIONS=noopt build

instead. This just breaks the interface. We could of course simply
just document that people should not do that… it's still a regression
from when people switched to dpkg-buildflags (me included).

(Or get the make bug #327154 fixed. :)

Rereading my mail again, it sounded a bit alarmist, the situation is
not *that* bad, as in the consequences on normal usage, it just affects
probably lots of packages, in case we care.

Thanks,
