--- Comment #8 from Ed Maste <emaste at freebsd.org> ---
It appears that each section is copied to the output binary at an offset
specified by the section's Addr, in an some (unspecified) order - i.e., both
.textdata and .zinfo specify an address of 0, and the output is .textdata
overlaid with .zinfo.
