[LEDE-DEV] [PATCH 1/2] Revert "linux: arc: disable kernel unwinding to fix modules loading"

[Alexey Brodkin]

This reverts commit acd41539d630688e9891003c9b51cace3e113316.

There's a fix in upstream that will at some point land in 4.4 stable as
well so we'll get rid of this hack and with the next commit will apply
upstream fix.
