# Hack: Since out of tree building of documentation is broken, make a out-tree
# build for mp versions and in-tree build for the regular binaries. Out of tree
# configure fails if in-tree configure run is detected, therefore force correct
# ordering by making config.status depend on build-tree-mp/config.status.
