abuild: checkdepends not installed

Created by: george-hopkins

When building packages, the checkdepends directive is not taken into account. According to the Alpine Linux wiki, the feature should be available for versions >=3.6. I'm not very familiar with the code base so this might be resolved automatically at some time in the future.

At the moment only libdrm is using this feature.

Example:

pkgname=checkdeptest
pkgver=0.1
pkgrel=0
pkgdesc="Test"
url="http://www.example.com"
arch="all"
license="GPL-3.0+"
depends=""
makedepends=""
checkdepends="nano"
source=""
builddir="$srcdir"

build () {
    true
}

check() {
    which nano
}

package() {
    true
}
