Subject: cdbs: Python cross building not supported
Package: cdbs
Version: 0.4.83ubuntu2
Severity: wishlist
When python is called to build C/C++ extensions whilst cross building a
package, it needs to be set up to use the cross toolchain, rather than the
default build host toolchain.
The patch below indicates how this might be done by adding an environment
variable to be set in the Makefile.
