In order to save space I did not change what we have. Every build starts from
a mrproper and new configuration. I can not mix LTO/non-LTO in this case. I'm
using upstream defconfig and upstream defconfig + LTO enabled and the result is
that spl increase in size for LTO building. I'm working to keep out
part that are not really needed but
I was hoping that LTO give me some help here
