Please refer to the manual pages of dpkg-buildpackage, sbuild or
pbuilder for how to perform a cross build. The relevant flag is either
--host-arch or --host.

It's not entirely clear whether you're referring to a manual cross build
here. If you do, you set up the CC, PKG_CONFIG etc. to point at your
cross toolchain. On a Debian system, you can simply prepend the GNU
triplet to your tools to obtain a cross toolchain (e.g. "gcc" becomes
"x86_64-linux-gnu-gcc" when building for amd64) if you install the
relevant packages (sbuild and pbuilder do that for you).

When using sbuild, you likely also want to use workarounds for #905345,
#905346, and #905347.

If that doesn't help, please include more details in your question.
