Bug#557248: libc0.1: [kfreebsd] remove() fails to remove directories

[Zack Weinberg <zackw@panix.com>]

Package: libc0.1
Version: 2.10.1-7
Severity: normal

The C standard requires remove() to delete both files and directories. 
This works correctly with the Linux kernel, but under kFreeBSD, remove() 
fails with "Operation not permitted" when applied to a directory. I'm 
not able to debug this in detail because gdb crashes and kdump hasn't 
been ported, but I would guess that remove() is calling unlink() and 
expecting that to return EISDIR, rather than EPERM, when applied to a 
directory.

This is the cause of, at least, FTBFS bug 537919.
