Hi Ian,
Good news!  Adding PHDRS section to the linker script resulted in a 
DragonFly kernel that boots and functions fine, including the kernel 
modules that we had trouble with before in gold 2.21.

I've attached the readelf output of the kernel built with ld and gold.
The main difference is the alignment value for the LOAD segments, but 
both have the first LOAD segment starting at the same address so I guess 
that's the important thing.

Thanks again,
John
