CONFIG_DEBUG_INFO_SPLIT will split debug info on
.dwo files. This will generate a smaller vmlinux and
smaller .ko modules, which will be easier to ship on
certain products.

CONFIG_DEBUG_INFO_DWARF4 will generate debug info in
DWARF4 format, which ends up being larger, but
improves the probability of resolving variables in
optmized code.

Nice, this makes my initramfs go down from about 17MB
to 4.7 MB :)
