Subject: Cross compile broken - 3.17.3 vs. 3.17.4?

Hello everyone,

when cross compiling with a rather generic x86_64-linux-gnu toolchain I 
run into the problem that "make bzImage" fails. It seems vmlinux binary 
gets run through the hosts objdump and not the $(CROSS_COMPILE)objdump 
as it was in 3.17.3.

I am not accustomed enough to kernel build habits to immediately spot 
the change that lead to this failed compile (178 files were changed 
between 3.17.3 and 3.17.4). But if you want, I am gonna provide you with 
a shell script that is able to set up the needed toolchain and succeed 
with 3.17.3 and fail with 3.17.4. Given my current workload this will 
take around 48 hours.

Regards,
Mattias
