Slind: armel toolchain & mktpkg(1)

I just finished patching mktpkg and dpkg-cross Slind tools to make it possible to bootstrap GNU EABI (armel) toolchain for OpenInkpot from source.

Just get dpkg, dpkg-cross and toolchain-package from our Git repository, build them and install to the Slind chroot.

Then get *-source-*.deb from packages and install to the Slind chroot too (not sure why pkg-config-source is marked as i386).

Now simple 'mktpkg armel' should bootstrap toolchain from source.
