[yocto] Tune qemuarm settings and build everything except the kernel?

Hello, all! I've recently been tapped to bootstrap an embedded Linux
project at work and create some demos on hardware left over from an
earlier effort. I normally work higher up the application stack,
compiling programs using a cross toolchain and sysroot created by some
unlucky coworker. In the past, I've just been given a VM and some code
to hack on, and instructions for cross-compiling it and getting it on
the target. Now I'm being asked to create that ecosystem for a small
team.
It hasn't yet been determined what the final hardware will be, so I
somehow need to create a framework to allow developers to start working
with these older systems, and 'port' it when the new hardware becomes
available. It seems the Yocto Project exists to solve exactly this sort
of problem, but... I don't quite know where to start.
On the plus side, the root filesystem for the old development kits
resides by default on an attached USB stick. I'm hoping I don't need to
mess with the old board's kernel at this early stage, as it already has
hardware-accelerated drivers and such that I'd rather not tangle with
unless/until necessary.
With that preamble, my question is: can I use Yocto/Poky to build a
cross-compiler, sysroot and root filesystem for an existing system
without also building the kernel? What do I need to type to make it
build everything *except* for the kernel?
I *did* manage to download poky-denzil-7.0.1 and run 'bitbake
core-image-minimal' after sourcing oe-init-build-env and setting MACHINE
to 'qemuarm' in conf/local.conf. After that, I copied everything in
tmp/work/qemuarm-poky-linux-gnueabi/core-image-minimal-1.0-r0/rootfs to
a USB stick and... it actually worked! It made me want to hug
Yocto/Poky. I'm all in!!
Now I'm wondering: is there any easy way to optimize for the actual
target(s) a bit more than the qemuarm MACHINE type does? The example
Makefiles for the old project all contain this line:
CFLAGS = -g -mcpu=arm1136jf-s -O2 -pipe
What's the best way to arrange for that '-mcpu' option to be used by all
recipes? Also, are there other optimizations I should consider? I'm
appending some details about the board in question, as well as the
complete output from booting it to a prompt. I'd be ever so grateful if
someone could recommend sensible base settings for this system, and
explain how to create a Poky 'layer', or 'machine'---or whatever the
right nomenclature is---to apply these settings.
Sorry for the long post, and thanks in advance for any advice!
