SDKIMAGE_FEATURES ??= "dev-pkgs dbg-pkgs src-pkgs 
${@bb.utils.contains('DISTRO_FEATURES', 'api-documentation', 'doc-pkgs', 
'', d)}"

SDKs by default contain debug symbols, and yes they can be used with gdb 
to debug on target.

If you don't want them in the SDK, remove dbg-pkgs (and src-pkgs whilst 
you're there) from SDKIMAGE_FEATURES.
