[PATCH 04/39] [media] DocBook/media/Makefile: Avoid make htmldocs to fail

[Mauro Carvalho Chehab]

If make is called twice like that:
        make V=1 DOCBOOKS=device-drivers.xml htmldocs

Make will fail with:

        make -f ./scripts/Makefile.build obj=scripts/basic
        rm -f .tmp_quiet_recordmcount
        make -f ./scripts/Makefile.build obj=scripts build_docproc
        make -f ./scripts/Makefile.build obj=Documentation/DocBook htmldocs
        rm -rf Documentation/DocBook/index.html; echo '<h1>Linux Kernel HTML 
Documentation</h1>' >> Documentation/DocBook/index.html && echo '<h2>Kernel 
Version: 4.2.0-rc2</h2>' >> Documentation/DocBook/index.html && cat 
Documentation/DocBook/device-drivers.html >> Documentation/DocBook/index.html
