package/v4l2loopback: fix v4l2loopback-ctl compile/install
Since upstream commit [1] the original v4l2loopback-ctl bash script was
replaced by a C version, so add a proper compile step (and remove bash
runtime dependency) to fix '[help] v4l2loopback package build fails for
raspberrypi5' [2].
The issue can be reproduced with the commands:
cat <<EOF >.config
BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_USE_ARCH_DEFAULT_CONFIG=y
BR2_PACKAGE_V4L2LOOPBACK=y
BR2_PACKAGE_V4L2LOOPBACK_UTILS=y
EOF
make olddefconfig
make v4l2loopback
Note: upstream commit [1] was introduced in version v0.13.0.
Buildroot bumped v4l2loopback to v0.13.2 in [3].
Fixes:
/usr/bin/install: cannot stat
