[Buildroot] [PATCH 1/1] board/raspberrypi: enable hdmi console for systemd

[Alexey Roslyakov]

Most of the users use HDMI console on RPi and with increasing popularity
of systemd they face a trouble.
systemd doesn't use /etc/inittab, enable getty@tty1.service instead.

Applied to master, but slightly reworked to avoid the nested if
condition:

 tty1::respawn:/sbin/getty -L  tty1 0 vt100 # HDMI console' ${TARGET_DIR}/etc/inittab
+# systemd doesn't use /etc/inittab, enable getty.tty1.service instead
+elif [ -d ${TARGET_DIR}/etc/systemd ]; then
+    mkdir -p "${TARGET_DIR}/etc/systemd/system/getty.target.wants"
+    ln -sf /lib/systemd/system/getty@.service \
+       "${TARGET_DIR}/etc/systemd/system/getty.target.wants/getty@tty1.service"
 fi

Thanks!
