Have you tried https://wiki.debian.org/CrossCompiling ? These kind of question would be better
answered in distro-specific maillist. 

If you are trying to cross-compiling glibc, best option would to use scripts/build-many-glibcs.py
script.  It does not tie with distro-source, so you will need to change the script to do
something different.
