This options adds a ton of debug symbols leading to *very* large
binaries:
5.2M kernel-module-8188eu_3.4.79-r0.8_olinuxino_a20.ipk
4.9M kernel-module-8189es_3.4.79-r0.8_olinuxino_a20.ipk
3.6M kernel-module-8192cu_3.4.79-r0.8_olinuxino_a20.ipk
After this change:
244K kernel-module-8188eu_3.4.79-r0.12_olinuxino_a20.ipk
224K kernel-module-8189es_3.4.79-r0.12_olinuxino_a20.ipk
208K kernel-module-8192cu_3.4.79-r0.12_olinuxino_a20.ipk
End users don't need such detailed debug symbols.
