I saw the ifdef in v4lchannel.h.
I presume that v4l is defined, so that the ifdef then includes videodev2.h
But the result is a duplicate inclusion.

AT LEAST FOR ME.... I have been building mythtv with the same scripts 
for over 10 years now, so I don't think that things have changed.
The first few lines of the call to configure are (for the laptop, Fedora 
23)
./configure    \
  --prefix=/usr/local        \
  --compile-type=release       \
  --qmake=/usr/bin/qmake-qt5 \
  --dvb-path=/usr/src/kernels/`uname -r`/include/uapi/ \
  --arch=x86_64              \
etc. etc.

So the header path *should be* correct....

Thoughts?
