Hi,

the GNU/Hurd platform is switching to a libio based glibc rather than
stdio right now.  So we need the following patch to make it work
(copied and shortened for the relevant cases only from src/s/gnu-linux.h):

(Mmh. Maybe it makes sense to collect all configuration specific to the
GNU C Library that is shared by all platforms supported by the GNU C
Library into a src/s/glibc.h file.)
