  The large /lib is indicative of a linux kernel config with too many modules.
Probably because you use a defconfig.  Do:
  make linux-menuconfig
and get rid of the modules you don't need.
Then, change your buildroot configuration to use a custom config instead of
a defconfig, and do
  make linux-update-defconfig
to save the custom config.

  Don't forget to wipe output/target/lib/modules before rebuilding,
or the old modules will just stay there...

  Yes!

  fonts seems a bit on the large side.  Check which font packages you have
selected.

  Make that ls -lRSh (so we get size in MB instead of bytes).
