[FFmpeg-devel] [PATCH] configure: Allow users to disable all hwaccel libraries

[Gyan Doshi]

I added --disable-hwaccels during configure and noticed that all 
autodetected hwaccel libs were still being linked - 6 in my case, which 
makes for a more bloated binary than warranted.

Turns out the option only disables native components which make use of 
the hwaccel libs. The reporter of ticket #3906 had a similar concern.

Added option to disable all autodetected hwaccel libs.

Regards,
Gyan
