gulkan fails to cross build from source, because it passes host compiler
flags to the build architecture compiler. For instance cross building on
amd64 for arm64 passes -mbranch-protection=standard and the amd64 gcc
doesn't like that. This is due to a recent change in dpkg's default
build flags. Looking closer this happens during the documentation build,
not while building the library. This build pass is only required for the
-doc package, so rather than fixing this, I suggest excluding this build
pass from an arch-only build (and cross builds always are arch-only).
Using reproducible builds, I verified that this change does not affect
package contents (compared a native full build to a native arch-only
build) and yes, this fixes the cross build. I note that this also speeds
up building on buildds, so that's a nice side effect. I'm attaching a
patch for your convenience.
