To answer this one myself: if one allows the Xen install to clone
the QEMU installation then

qemu-xen-dir-remote

is named of the directory that gets created by a script, howver
within the script the name comes from a ${QEMU_DIR}-remote
construct, hence it not being visisble to a plain text search across
the source tree, except at the point where the Makefile references it.
