Subject: media-video/mpv: add compiler check when vaapi is enabled with egl
X-Git-Url: http://git.tremily.us/gitweb.cgi?a=commitdiff_plain;h=2c5623d06461349a05557f354bbc6bf5f4192269;p=gentoo.git

media-video/mpv: add compiler check when vaapi is enabled with egl

VAAPI + EGL combo requires Thread Local Storage C++11 feature or
GNU __thread extension. Add the corresponding check for sanity.
