That's my point, this appears to be one place where Linux for i386 and
PPC differ.

On my Athlon system, there is a comment in /usr/include/sys/io.h :

   Portability note: not all Linux platforms support this call.  Most
   platforms based on the PC I/O architecture probably will, however.
   E.g., Linux/Alpha for Alpha PCs supports this.  */

So my point is no matter what glibc package is installed, any Linux distro
for the PPC platform will not have that file. The debian PPC list archives
confirmed this:

http://lists.debian.org/debian-powerpc/2000/debian-powerpc-200012/msg00711.html

I noticed that there is a #ifndef MACOSX at the top of z_lp.c. Is there
any symbol on Linux that specifies if it's PPC or not? It may be a simple
as adding another #ifndef
