I think the correct way would be to use libbfd to achieve something
similar to the following in "shell notation":

| objdump -t vmlinux| grep " system_utsname"
102860c0 g     O .data  00000186 system_utsname
^ start                 ^ size
| objdump --start-address=0x102860c0 --stop-address=0x10286246 vmlinux
...

Using libbfd it should be feasible to read a "struct new_utsname"
from the binaries. Sorry, but don't have the time for a better
proof-of-concept than using objdump today.
