bzlib and lzma are libxc dependencies now, so firstly you have to add
the two libraries to the stubdom build system, take a look at
pciutils in stubdom/Makefile, that is a good example of how a new
library is added.
Then you also need to add them both at least to the libxc target, take a
look at zlib (and cross-zlib), that should be close to what you need.
Finally you need to tweak the libxc Makefile for the stubdom case so
that the two libraries are correctly added to zlib-options.
Have fun! ;)
