    Description

      Steps to reproduce:
      1) Start installing Moodle on the system without curl PHP extension (in my case it was a Debian Linux box without php5-curl package installed).
      2) After accepting license agreement you get redirected to "Server checks" page (/admin/index.php?cache=0&lang=en&agreelicense=1).

      Expected behavior:
      The page should load properly and display the information about missing curl extension.

      Actual behavior:
      In production environment this page is blank (because of disabled error reporting in PHP). In development environment with E_ALL error reporting level this page displays the following error:

      PHP Fatal error: Call to undefined function curl_version() in /path/to/moodle/lib/upgradelib.php on line 2334

      The problem is caused by changes introduced recently in MDL-55777:
