autoconf.h error cross compiling

[Lee Revell <rlrevell@joe-job.com>]

I am trying to cross compile alsa-lib 1.0.11 for a PPC 440 embedded
system.  The build fails with this error:

Why is it looking for autoconf.h?  AFAICT that is a kernel header.  Do I
merely have to copy it into the powerpc-440-linux-gnu/sys-include/linux/
directory?

Is the bug in my toolchain or alsa-lib?
