OK, the check in acinclude.m4 is correct (it is an either/or thing).  I
looks like its probably that qcam uses outb and inb but doesn't link in
sanei_pio.  That file appears to have some logic to handle platforms that do
not define those functions.

I'll submit a fix to backends/Makefile.am to start linking this in.
