That's a long-standing problem we discussed in quite a detail some time ago, see
http://lists.busybox.net/pipermail/buildroot/2016-May/161785.html?and
http://lists.busybox.net/pipermail/buildroot/2016-June/162461.html

I've just sent a patch with Thomas' solution to the problem at hand,
pls find it here -?http://patchwork.ozlabs.org/patch/697273/
