Subject: [PATCH 4.14 198/246] microblaze: Fix simpleImage format generation

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Michal Simek <michal.simek@...inx.com>

[ Upstream commit ece97f3a5fb50cf5f98886fbc63c9665f2bb199d ]

simpleImage generation was broken for some time. This patch is fixing
steps how simpleImage.*.ub file is generated. Steps are objdump of
vmlinux and create .ub.
Also make sure that there is striped elf version with .strip suffix.
