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.

+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.
+ HOSTCC arch/powerpc/boot/addnote
+ HOSTCC arch/powerpc/boot/hack-coff
+ DTC arch/powerpc/boot/taishan.dtb
+ HOSTCC arch/powerpc/boot/addnote
+ HOSTCC arch/powerpc/boot/hack-coff
+ MODPOST 800 modules
+ fixdep: error opening depfile: arch/powerpc/boot/.hack-coff.d: No such file or directory
+ scripts/Makefile.host:91: recipe for target 'arch/powerpc/boot/hack-coff' failed
+ make[5]: *** [arch/powerpc/boot/hack-coff] Error 2
+ make[5]: *** Waiting for unfinished jobs....
+ fixdep: error opening depfile: arch/powerpc/boot/.addnote.d: No such file or directory
+ scripts/Makefile.host:91: recipe for target 'arch/powerpc/boot/addnote' failed
+ make[5]: *** [arch/powerpc/boot/addnote] Error 2
+ rm arch/powerpc/boot/taishan.dtb
+ arch/powerpc/Makefile:263: recipe for target 'cuImage.taishan' failed
+ make[4]: *** [cuImage.taishan] Error 2
+ make[4]: *** Waiting for unfinished jobs....
+
+Add a GNU make specific .NOTPARALLEL pseudo rule to enforce sequential building
+of the addnote, hack-coff and mktree executables.
