The best solution would be to get aws to install versioned libraries but if that's not an option, you probably want to package the .so files in the actual library package, not the -dev package (which is the default since usually .so are symlinks for development and the actually versioned ).

Thanks for the tips, Jussi.
I'm managing to get a little further, added
INSANE_SKIP_${PN}-dev += "dev-elf"
FILES_${PN}-dev += "${libdir}/libaws-cpp-sdk-core.so ${libdir}/libaws-cpp-sdk-s3.so"
FILES_${PN} += "${libdir}/libaws-cpp-sdk-core.so ${libdir}/libaws-cpp-sdk-s3.so"

and now the package_qa succeeds, but when I try to build the full system image I get:

ERROR: core-image-wg2xx-1.0-r0 do_rootfs: Unable to install packages. Command '/home/colin/fsl-community-bsp/build/tmp/sysroots/x86_64-linux/usr/bin/apt-get  install --force-yes --allow-unauthenticated  .....' returned 100:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 packagegroup-my-apps : Depends: aws-sdk but it is not installable
E: Unable to correct problems, you have held broken packages.

Perhaps the INSANE_SKIP is un-necessary/over-zealous, but I didn't yet manage to get through the package_qa without it. 
(Admittedly, I wasn't *100%* sure of what you were suggesting...)
