From 38a8cea063ee25971bc5a9e8842edda280ed8513 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Wed, 4 Jan 2017 10:42:28 +0100 Subject: [PATCH] powerpc: boot: fix build with parallel make The powerpc boot wrapper Makefile is not parallel build safe, causing fixdep to fail reading dependency files of the addnote, hack-coff and mktree utilities when concurrently building different image targets. A typical failure looks like: Building modules, stage 2.
