[PATCH] firmware: Create directories for external firmware

From: Michal Marek
Date: Tue Jul 08 2014 - 08:47:35 EST

Commit 5180d5f4 ("firmware: Simplify directory creation") broke
including firmware specified in CONFIG_EXTRA_FIRMWARE:

MK_FW firmware/amd-ucode/microcode_amd.bin.gen.S
/bin/sh: firmware/amd-ucode/microcode_amd.bin.gen.S: No such file or directory
firmware/Makefile:185: recipe for target
'firmware/amd-ucode/microcode_amd.bin.gen.S' failed

It works with O= builds, because the directory is created by
Makefile.build. Create the directory in firmware/Makefile in non-O

Ronald, can you tell me your full name for the Reported-by: line?
