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.

Add a GNU make specific .NOTPARALLEL pseudo rule to enforce sequential building of the addnote, hack-coff and mktree executables. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
