Doesn't build on GNU/Hurd with glibc based on libio

[Marcus Brinkmann]

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.)

Thanks.

Just to be sure: will this patch work for all versions of GNU/Hurd, 
including the older ones, at least as well as with the current version
of the s/gnu.h header?

Yes, if you compile it with the old version, neither _IO_STDIO_H nor
_STDIO_USES_IOSTREAM will be defined, and the code will compile and run, too.

Thanks,
Marcus
