[LEDE-DEV] Build fails with missing libgcrypt dependency

[Mauro Mozzarelli]

Two days ago I have done a fresh git pull (from scratch) and I built 
LEDE without errors (well mwan3 still not working, but that is a 
different matter because LEDE did build).

After the latest update done just right now, LEDE fails to build with 
the following:

Configuring kmod-usb-storage-extras.
Configuring xz-utils.
Configuring zip.
Configuring openvpn-mbedtls.
Configuring luci-app-hd-idle.
Configuring dsl-vrx200-firmware-xdsl-b-patch.
Configuring ppp-mod-pppoa.
Configuring ppp-mod-pppoe.
Configuring luci-app-openvpn.
Configuring kmod-ledtrig-netdev.
Configuring dnsmasq-full.
Collected errors:
  * satisfy_dependencies_for: Cannot satisfy the following dependencies 
for ntfs-3g-utils:
  *     libgcrypt *
  * opkg_install_cmd: Cannot install package ntfs-3g-utils.
