Subject: sdk: include arch/arm/ Linux includes along with arch/arm64/ ones
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4bb8a678e0e0eaf5c3651cc73f3b2c4cb1d267a2;p=openwrt%2Fstaging%2Fblogic.git

sdk: include arch/arm/ Linux includes along with arch/arm64/ ones

The Linux headers on arm64 architectures contain references to common
arch/arm/ headers which were not bundled by the SDK so far.

Check if we're packing the SDK for an arm64 target and if we do, also
include arch/arm headers as well.

Fixes FS#1725.
