No, maybe not, I usually cross-compile, so speed does not matter too much.
If you only want to build for atari, edit:
debian/config/m68k/define
and comment out all flavours except atari. Then start the build:
debuild -B -am68k
-B to only build the binaries, no source packages, -am68k if you want to
cross-compile, can be omitted on an m68k box.
The build will apply the debian and m68k specific patches and create a dir
debian/build/build_m68k_none_atari
together with the config for atari. Once you have that directory, you can
stop the build and build the old fashioned way with make vmlinux in that
directory.
There might be a shortcut to get to that point, but normally the debian
build deletes everything in debian/build and starts to apply the patches
from scratch, assembles the config file, and then starts to build binaries,
headers, docs, etc. So build_m68k_none_atari is the directory you want, and
perhaps you want to move it outside the debian source directory, since the
debian scripts erase it if you should, by mistake, start to build the debian
way again.
