[libvirt] [PATCH] doc/Makefile.am: Add checking of XHTML1 DTD.

[taget at linux.vnet.ibm.com]

From: Eli Qiao <taget at linux.vnet.ibm.com>

When generating html from html.in, even not install xhtml1-dtds.noarch, make will not return a error.
which will lead 'make install' failed.

This patch return error when creating html doc when doning make, will give user a correct error message.
