OpenWrt support for Linksys MX4200

How long does it take to compile @qosmio build? I have a powerful machine but it's running for a while.

❯ git clone https://github.com/qosmio/openwrt-ipq mx4300 -b qualcommax-6.x-nss-mx4300

❯ cd mx4300

❯ ./scripts/feeds update

❯ ./scripts/feeds install -a

❯ cp nss-setup/config-nss.seed .config

❯ make defconfig V=s -j4

❯ make

It's been compiling for more than 30 minutes now. Is this normal?
