Subject: Add target devhelp2 only when xsltproc has been found
X-Git-Tag: dbus-1.13.10~13^2~6
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e840edec094ee80d2ca4a0f7e77bed039a3a1d55;p=thirdparty%2Fdbus.git

Add target devhelp2 only when xsltproc has been found

It doesn't make sense to add a make target if it can't be created.
