[Libva] Gstreamer-vaapi: about the option --with-gstreamer-api

[Lim, Siew Hoon]

Hi,

--with-gstreamer-api is not valid option in gstreamer-vaapi anymore but I found out that debian.upstream/rules file still got this option. 
Is this "--with-gstreamer-api" option still valid need to be using in debian.upstream/rules file?  
I remove out and compile the code and install don't see any issue. Can we remove it?

# Allow HTML documentation build
indep_conf_flags = \
        --with-html-dir=\$${prefix}/share/doc/$(DEB_SOURCE_PACKAGE) \
        --with-gstreamer-api=$(GST_API_VERSION)


Thanks.
