fakeroot make-kpkg is broken in 3.14

[Alexei Starovoitov]

It seems commit f4d4ffc03efc ("kbuild: dtbs_install: new make target")
breaks 'fakeroot make-kpkg' package creation on ubuntu.
Didn't investigate the root cause yet, just heads up.

The errors I see:

Alexei,

Thanks for the heads up.

Grant's version differs significantly from what I had proposed.  Which
isn't a big deal, except that I'm not familiar with why he added the
'prepare' target to dtbs dtbs_install.  It's also clear from the patch
that he is _much_ more familiar with the guts of the kernel Makefile
system than I am ;-)

This really doesn't tell us much as I'm not familiar with make-kpkg and
the assumptions it makes.  Please provide more details once you've
investigated a bit more.

On a side note: It's a bit concerning to see make-kpkg grepping the
config.  In general, one should directly test for features as config
symbols are not ABI and can change at any time.

thx,

Jason.

looks like it's a problem of make-kpkg itself.
It's doing:
./kernel/ruleset/misc/version_vars.mk:
HAVE_INST_PATH  =$(call doit,grep -E '\(INSTALL_PATH\)' Makefile 2>/dev/null )
which is now being true and it triggers different path through package build.
Ccing Manoj who's the author of this stuff.

I think this issue will affect ubuntu guys.

        I am afraid kernel-package has long need some attention; I am
 hoping to be able to do so in the coming month.
