yes thanks for the report,

the fix is already baking in apparmor-next
c2489617b3b9 apparmor: Fix undefined reference to `zlib_deflate_workspacesize'

this happens when CONFIG_SECURITY_APPARMOR_EXPORT_BINARY is not set and hence ZLIB_INFLATE/DEFLATE aren't selected and the kernel is configed without them. Basically some blocks of code need to be wrapped in #ifdef.
