bug#8577: GNU coreutils-8.12 thinks GNU libc-2.13's getcwd() is "buggy" ?

[Jason Vas Dias]

Hi - Having just built GNU coreutils-8.12 against GNU libc 2.13, 
coreutils SKIPS a test normally run as part of "make check"
because "system getcwd() is buggy" :
(after coreutils-8.12  'configure' and 'make -j2' succeeds :)
$ make check
...
./misc/pwd-unreadable-parent: skipping test: can't use buggy system getcwd
SKIP: misc/pwd-unreadable-parent

I think it's a shame that the latest stable GNU coreutils thinks the latest 
stable GNU 
libc's getcwd() is "buggy" . Why is this ?  Why not get glibc fixed if it is 
"buggy" before
releasing a coreutils that complains about it ?

I'll investigate further - I don't know if this is a glibc bug or a coreutils 
bug so I raised
glibc bug #12713 about this also.

Just though I'd should let you know,
and thanks for an otherwise flawless coreutils,
