[yocto] Custom recipe - resolving "do_package_qa: QA Issue: -dev package contains non-symlink .so"

[colin.helliwell at ln-systems.com]

I have a custom recipe (for the AWS SDK), which is failing at the package_qa
stage.
The recipe is a very basic cmake styley, and on its own seems to begin with:
'bitbake -f -c package aws-sdk'  completes without errors.

But for 'bitbake -c package_qa aws-sdk) I get: 

ERROR: aws-sdk-1.1.31-r0 do_package_qa: QA Issue: -dev package contains
non-symlink .so: aws-sdk-dev path
'/work/armv7a-neon-poky-linux-gnueabi/aws-sdk/1.1.31-r0/packages-split/aws-s
dk-dev/usr/lib/libaws-cpp-sdk-core.so'
-dev package contains non-symlink .so: aws-sdk-dev path

dk-dev/usr/lib/libaws-cpp-sdk-s3.so' [dev-elf]

I'd appreciate help with resolving this. Thanks.
