libvirt/docs/apibuild.py
Guido Günther 214c226f9e Unbreak rebuilding docs with release tarballs 
Release tarballs ship the include/libvirt/libvirt-common.h.

when srcdir != builddir we end up including libvirt-common.h twice: from
$top_srcdir/include/libvirt-common.h and from
$builddir/include/libvirt-common.h leading to

  function virTypedParamsGetUInt from /tmp/buildd/libvirt-2.4.0/debian/build/docs/../include/libvirt/libvirt-common.h redeclared in /tmp/buildd/libvirt-2.4.0/docs/../include/libvirt/libvirt-common.h
  function virTypedParamsAddBoolean from /tmp/buildd/libvirt-2.4.0/debian/build/docs/../include/libvirt/libvirt-common.h redeclared in /tmp/buildd/libvirt-2.4.0/docs/../include/libvirt/libvirt-common.h
   …

Only add the builddir to the search list if there is no pregenerated
libvirt-common.h.

Reuse the existing check that predates the libvirt.h → libvirt-common.h
split and that probably was meant for exactly that.
