Subject: [PATCH] kbuild: deb-pkg: Add libdw-dev:native to Build-Depends-Arch

The dwarf.h header, which is included by
scripts/gendwarfksyms/gendwarfksyms.h, resides within the libdw-dev
package.

This portion of the code is compiled under the condition that
CONFIG_GENDWARFKSYMS is enabled.

Consequently, add libdw-dev to Build-Depends-Arch to prevent
unforeseen compilation failures.

Fix follow possible error:
  In file included from scripts/gendwarfksyms/cache.c:6:
  scripts/gendwarfksyms/gendwarfksyms.h:6:10: fatal error: 'dwarf.h' file not found
