Source: libselinux

Hi,

libselinux broke cross compilation. It now uses the build architecture 
toolchain. I tracked it down to
https://salsa.debian.org/selinux-team/libselinux/-/commit/75ab1387129f90dd910aa1f20f399ebd126379f9 
where CC stops being exported.

I propose telling dpkg's builtools.mk to export the variables. Please 
find a patch attached.

Helmut
