This is a side effect of the loader gaining the ability to boot from 
GELI encrypted partitions.

You can compile with LOADER_NO_GELI_SUPPORT to disable this to get back 
to a smaller one if you need.

Maybe we should be putting the GELI enabled boot blocks in a different 
filename? I generally wanted to avoid creating a new version of each 
bootcode with GELI support.

My goal somewhere down the road is to create a single bootcode that can 
do UFS and ZFS, then maybe we can have gptboot and gptgeliboot or something.
