[PATCH xserver 5/5] dmx/doc: alert builder when a tarball cannot be created

[Gaetan Nadon]

When the html files cannot be doxygen generated, the makefile
target dist or distcheck will fail, as designed. Output a message
for the builder to figure out why this is happening, as it just
look like any other makefile failure.
