I suppose so. You won't get far without that.

The current list for sbuild, is:
Ubuntu precise:
armel: dpkg-cross, g++-arm-linux-gnueabi, libc6-dev-armel-cross, pkg-config-arm-linux-gnueabi
armhf: dpkg-cross, g++-arm-linux-gnueabihf, libc6-dev-armhf-cross, pkg-config-arm-linux-gnueabihf
Debian Wheezy:
armel: dpkg-cross, c++-compiler-arm-linux-gnueabi, linux-libc-dev-armel-cross
armhf: dpkg-cross, c++-compiler-arm-linux-gnueabihf, linux-libc-dev-armhf-cross
mips: dpkg-cross, c++-compiler-mips-linux-gnu,  linux-libc-dev-mips-cross
mipsel: dpkg-cross, c++-compiler-mipsel-linux-gnu,  linux-libc-dev-mipsel-cross
powerpc: dpkg-cross, c++-compiler-powerpc-linux-gnu,  linux-libc-dev-powerpc-cross
ia64: dpkg-cross, c++-compiler-ia64-linux-gnu,  linux-libc-dev-ia64-cross

dpkg-cross is there for the autotools/cmake cross-config support, not the cross-library-mangling

Debian doesn't yet have the pkg-config-<triplet> packages. That needs fixing too, along with
getting some cross-toolchains built

OK. Although it's just a text file/depends list. It can be maintained anywhere. It may be
problematic to have it in debian when the cross-compilers themselves are not there yet (only in
emdebian toolchain repo) - a package can't depend on things that don't exist.
