[Bug libc/10939] New: glibc does not support linux ERFKILL errno

["nelhage at mit dot edu" <sourceware-bugzilla at sourceware dot org>]

glibc doesn't include the "ERFKILL" errno in its error tables. As of Linux 2.6.31 
(specifically, commit 1f87f7d3a3b42b20f34cb03f0fd1a41c3d0e27f3), the Linux kernel 
will return this error number for operations on wireless devices when the rfkill 
switch is enabled, this results in confusing error messages from 'iwconfig' or 
other commands (specifically, things like "SIOCSIFFLAGS: Unknown error 132")

e.g. http://ubuntu-virginia.ubuntuforums.org/showthread.php?t=1271226 shows two 
users whose wireless cards don't work and are unable to diagnose the problem as a 
result of this error message.
