bug#18896: regressions in coreutils 8.23 on Yosemite

[Jack Howarth]

   I am finding that the single failure seen on Mavericks for the 
coreutils 8.23 testsuite...

FAIL: test-getcwd.sh

=====================================================
   GNU coreutils 8.23: gnulib-tests/test-suite.log

when run as sudo, is replaced by two new errors and two new failures
under Yosemite as sudo.

link-deref.sh: set-up failure:

Are these failures already known and are there any workarounds? I have attached
the bzip2 compressed test-suite.log in case it helps.
     Thanks in advance
