Subject: x86: Use $(OBJDUMP) instead of plain objdump
From: Chris Clayton <chris2553@xxxxxxxxxxxxxx>
commit e2e68ae688b0a3766cd75aedf4ed4e39be402009 upstream.
commit e6023367d779 'x86, kaslr: Prevent .bss from overlaping initrd'
broke the cross compile of x86. It added a objdump invocation, which
invokes the host native objdump and ignores an active cross tool
chain.
Use $(OBJDUMP) instead which takes the CROSS_COMPILE prefix into
account.
[ tglx: Massage changelog and use $(OBJDUMP) ]
Fixes: e6023367d779 'x86, kaslr: Prevent .bss from overlaping initrd'
