This error suggests that Jos has an wrong/obsolete version of <asm/unistd.h>
where __NR_sysinfo is defined (at least in all linux-1.3.*/include/asm-i386
subdirs I currently have access to).

So configure should also check for availability of the sysinfo system call.

The sysinfo(2) man pages states in the BUGS section that there is no prototype
for sysinfo in the DLL 4.4.1 libc; nm libc.a | grep sysinfo shows that there
isn't a sysinfo function in libc5 either.

I'll forward that one to H.J.Lu if it didn't happen yet. (Have to look into the
bugs db when phone rates drop tonight)

Thanks
  Siggy (new libc maintainer)
