rm cannot delete directory symlinks with new coreutils

[augiedoggie]

It seems as though the new coreutils added in hrev36275 is unable to delete symlinks which point at a directory. I first noticed the problem when trying to use the setgcc command which failed with:

rm: cannot remove `/boot/develop/abi//current': Is a directory
Failed to set GCC x86/gcc4.

The problem can also be seen with:

mkdir dir ; ln -sf dir symdir; rm symdir

using rm fails with 'Is a directory'. using rm -r fails with 'Not a directory'

Should be fixed in hrev36331. fstatat was reversing the traverse symlink meaning, hence finding out a directory and not a symlink.

Nice work! Thanks.

I think this has also fixed an annoying problem when using mercurial with the Haiku repository.
