This shouldn't be needed anymore, we build our own version there, if
need be. If you have one of these "lzma e" flavour binaries, please
flesh out toolchain/dependencies/check-host-lzma.sh
instead (See TODO in there). TIA.

I'm not sure if that is a good idea. You'd generally want to build all
packages as ipkg, i'd say.

wow. This would be very intrusive. We should be able to use one central
TARGET_PACKAGES_DIR that may or may not be empty that we stick into the
individual FOO_DIR's via TARGET_DIR

But first  we have to fix the lib vs. lib64 dir glitch with gcc, that's
more important. And then it would be nice if somebody would look into
multilib support, which is apparently broken since several years (way
before i joined).

Still, creating ipkg would be a nice thing to have.
