TYPO3 Core

This is what I'm getting in addStyleSheetDirectory() (just before addCssFile):

array(5 items)
   func_get_args() => array(1 item)
      0 => "/var/www/html/typo3_master/typo3/sysext/t3skin/Resources/Public/Css/" (68 chars)
   $path => "/var/www/html/typo3_master/typo3/sysext/t3skin/Resources/Public/Css/" (68 chars)
   $cssFile => "backend.css" (11 chars)
   PathUtility::getRelativePathTo($path) . $cssFile => "sysext/t3skin/Resources/Public/Css/backend.css" (46 chars)
   PathUtility::getAbsoluteWebPath($path . $cssFile) => "/typo3/sysext/t3skin/Resources/Public/Css/backend.css" (53 chars)

my TYPO3 is set up as:

/var/www/html/typo3_master/
    typo3 -> typo3_src/typo3
    typo3_src -> /var/www/typo3/TYPO3.MASTER/typo3

where /var/www/TYPO3.MASTER is a local TYPO3 master git

I'm not running composer mode.
