linux-next: build failure after merge of the kbuild tree
From: Stephen Rothwell

After merging the kbuild tree, today's linux-next build (x86_64
allnoconfig) failed like this:
make: *** No rule to make target 'scripts/mod/empty.o', needed by '__build'.
Caused by commit
624a912f84bc ("kbuild: detect objtool changes correctly and remove .SECONDEXPANSION")
(at least, reverting that commit fixes it)
I use a separate object directory and, in this case, it is newly created.
A build with V=1 and -s removed (and no -j) gives this around the
make -f /home/sfr/next/next/scripts/Makefile.build obj=scripts/mod
make: *** No rule to make target 'scripts/mod/empty.o', needed by '__build'. Stop.
make: *** [/home/sfr/next/next/Makefile:1309: prepare0] Error 2
I have reverted that commit for today.
