Describe the bug
Projects which have latex_elements = { 'classoptions':',oneside', } will output irrelevant warnings about useless options. For example:

Package Fancyhdr Warning: \fancyfoot's `E' option without twoside option is use
less on input line 536

To Reproduce

$ git clone https://github.com/arm-software/ebbr
$ cd ebbr
$ make latexpdf

Expected behavior
Should not get warnings from the Fancyhdr package.

Environment info

  • OS: Linux
  • Python version: 3.7.3
  • Sphinx version: mainline

I've got a fix for this bug. I'll post it shortly.

Fix 'oneside' latex output
add7035 
Sphinx.sty had an FIXME bug where documents with the 'oneside' option
would output lots of the following warnings when building the document:

   Package Fancyhdr Warning: \fancyfoot's `E' option without twoside
   option is useless on input line 309.

Fix the problem by using \if@twoside around the offending tex code that
tries to set format for the even pages. 'Even' pages don't exist on
oneside builds, which causes the warning to be emitted.

Fixes: sphinx-doc#8215
