The kernel source represents all of our flavours at once and therefore
any configuration change via edit there is about all of them.  You can
change individual items by appending the new value to the per flavour
configuration files as below:

    debian.master/configs/<arch>/config.flavour.<flavour>

then run fakeroot debian/rules updateconfigs

By default when you build (dpkg-buildpackage -b) you are building all of
the flavours for the architecture of the chroot you are building in.
