 As i see only one: amd64.amd64 package has CONFIG_DEBUG_INFO=y while
amd64.i386 has CONFIG_DEBUG_INFO is not set ... diff says only this:

< CONFIG_DEBUG_INFO=y
< # CONFIG_DEBUG_INFO_REDUCED is not set
< # CONFIG_DEBUG_INFO_SPLIT is not set
< # CONFIG_DEBUG_INFO_DWARF4 is not set
---
> # CONFIG_DEBUG_INFO is not set

 But also affected 686-pae has CONFIG_DEBUG_INFO=y too, so i guess that config
option is not an issue.
