[meta-ti] Stumped. Can't get 2.6.37 TI kernel to boot when built with toolchain from denzil or Linaro gcc-linaro-arm-linux-gnueabihf-4.8-2013.07-1_linux/

OK, I'm in a little new territory here.  I've been attempting to add
machine support to my oe_core + meta-ti master checkout.  I've setup the
machine conf for c6a816x-evm and all the associated files using denzil as a
base.  I modified the 2.6.37 recipe to use my custom boards kernel instead
of the one from git (set SRC_URI to my .tar.bz2).  I stubbed out u-boot for
now as it was giving me problems.

First question.  I looked at my poky/meta/recipes-kernel/linux-libc-headers
dir of a denzil checkout that last had c6a816x-evm support to use as kind
of an example/guide.  I see recipes for linux-libc-headers_3.2.bb and
linux-libc-headers_3.0.8.bb.  Do I need to create a recipe for 2.6.37 and
set the SRC_URI for a 2.6.37 commit so that my rootfs packages will be
built against headers that match the version of the kernel I'm using?  It
looked like linux-libc-headers.inc has some kind of check to decide on
which headers to use (3 or 2.6) but I don't quite follow how it works yet.

Second question.  When I try to bitbake core-image-minimal after adding in
my kernel (a tar.bz2), it builds but the do_package phase gets errors:

Build Configuration:
BB_VERSION        = "1.19.1"
BUILD_SYS         = "x86_64-linux"
NATIVELSBSTRING   = "Debian-7.1"

I did some searches of this kind of error and mostly found noise but also
found some references to  INHIBIT_PACKAGE_STRIP but I'm not sure if that
will fix this problem or not.

So far my deploy dir has a uImage but not the rootfs tar or images. I hope
fixing the above will get me there.
