It would make sense in certain cases, but not in others...
This should really be up to the site to decide on this.
Question is what EasyBuild v3.0 should do by default: should the
toolchain module define $CC, $CFLAGS & co or not?
Oh yes, and someone should modify the Toolchain easyblock to include
this information in the generated module file. ;-)

Maybe I'm misunderstanding but that is pretty much exactly why I
'created' the trivial buildenv easyblock. The users just load the
module that gets created and they can simply use $CC and friends
in their build processes, making switching toolchains very
straightforward.

From a user perspective it would be more interesting to have
this option under Lmod than EB. The end user is most likely to
interact only with the environment modules manager than EB
directly. The idea would be that the user loads all the
modules he/she needs according to a specific toolchain and can
get all the linking flags by calling something like:
$module -L
In this way the user can use command substitution directly
into Makefiles. More importantly, this should also take into
account ordering the lib flags accordingly since sometimes
order is essential for successful linking.
That is something that we discussed internally since this
functionality is provided by our current modules manager
(although in a very primitive way) and would be lost when
transitioning to Lmod.

I'd definitely like to see it as an option. For testing,
--dump-env-script on
ImageMagick-7.0.3-2-intel-2016b.eb would be a good start.
I'd like to
see _everything_ set in that .env instead set in the
modules first... as
just a
start.
Beyond that, I'd also like to see a line with -lX11 -lXabc
-lX123 so I
don't need to
remember the name of all the X11 libs.
But it should be a site (or user) selectable option (I
could see some
people not wanting such things).
