#2 Bogus /dev/video check

[Mark Brown]

Attempting to configure on my 2.4.9 system with devfs
fails with:

checking for Video4Linux device...
configure: error: Oops! No Video4Linux device
(/dev/video) found!

The first video device appears as /dev/video0.

In any case, this check seems bogus since it prevents
compilation on a system without a video4linux device
present. That seems a perfectly reasonable thing to
do - using a beefier machine than the one you want to
run on or using build server for porting packages for
a distribution spring to mind as motivations for
doing things other ways.

On further investigation it seems that configure is
actually checking for /dev/video0 but it is checking for
writability which fails. The attached patch should fix
that, though I still feel that this check is bogus and
should at most be a warning.

Trivial patch

Closing bugs without comment is rather rude.
