Subject: [PATCH] build: don't fail when xsltproc is missing

On a machine without xsltproc, the build failed with:

Scripting search.php
/usr/local/bin/bash: line 1: search.php.tmp: No such file or directory
rm: ./search.php: No such file or directory

Regression introduced in commit 28183590.

* docs/Makefile.am (%.php): Skip in the same conditions when the
.tmp file is skipped.
