close PR docs/66264

[Cleaning out gnats]
The pr docs/66264 , also found here: 
http://www.freebsd.org/cgi/query-pr.cgi?pr=docs/66264 can be closed. The 
PR mentions a couple of spelling- and mdoc-fixes to the rtld(1) manual 
page. The changes have not been merged to RELENG_4, but are merged to 
RELENG_[5,6] and HEAD and since RELENG_4 is close to EOL I don't think 
it necessary to merge the changes. If somebody thinks different there is 
a patch in the PR with the changes.
