Comment:
I successfully built the package with a following script:
```
#!/bin/sh
set -x
set -e

function __BUILD__() {
	git clean -fdx -e /hostdir
	case "$1" in
		i686) bootstrap=i686;;
		*-musl) bootstrap=x86_64-musl;;
		*) bootstrap=x86_64;;
	esac
	shift
	./xbps-src binary-bootstrap "$bootstrap"
	./xbps-src -j4 "$@" pkg zbar
}

wget  -N "https://alpha.de.repo.voidlinux.org/static/xbps-static-latest.x86_64-musl.tar.xz"
mkdir -p xbps
tar xf xbps-static-latest.x86_64-musl.tar.xz -C xbps
export PATH="$PWD/xbps/usr/bin:$PATH"

(cd void-packages && git pull origin master) ||
git clone --depth 1 git@github.com:hadrianw/void-packages.git

cd void-packages

for arch in x86_64 x86_64-musl i686; do
	__BUILD__ "$arch" || failed="$failed $arch"
done
for arch in aarch64 armv7l armv6l-musl aarch64-musl; do
	source "common/cross-profiles/$arch.sh" &&
	__BUILD__ "$arch" -a "$arch" || failed="$failed $arch"
done

echo Failed:$failed
```

I attach the build log.
```hadrian@karton $ ./check.sh &> build.log```
