re: port-shark/43652: savecore does not work

[matthew green <mrg%eterna.com.au@localhost>]

i setup a dump partition on my shark and fired off atf-run but it
didn't startup due to my system being NFS based:

7oclock /usr/tests# atf-run
Content-Type: application/X-atf-tps; version="2"

info: atf.version, Automated Testing Framework 0.10 (atf-0.10)
[ ... ]
tps-count: 229
terminate called after throwing an instance of 'atf::system_error'
  what():  atf::atf_run::set_immutable(/tmp/atf-run.01203a): 
chflags(/tmp/atf-run.01203a) failed: Operation not supported
Abort (core dumped)
1.292u 3.888s 0:06.69 77.2%     0+0k 0+0io 0pf+0w


(i should probably file a PR about this, but maybe you can just
fix it really quickly ;-)
