[Buildroot] [PATCH v1 1/1] vidstab: new package

[Steve Kenton]

	  Vid.stab is a video image stabilization library
	  that can be used with ffmpeg --enable-libvidstab
	  and is acknowledged by the ffmpeg developers to
	  be superior to the built-in deshake filter. It
	  works best in a 2-pass configuration but 1-pass
	  is also available when needed/acceptable.

I'm planning on using this with ffmpeg but that part is not
ready yet, however libvidstab.so is standalone if others are
interested in using it. It builds with uClibc,  ucLibc-ng,
musl and glibc with just C++ enabled. I know it's late in
the cycle so kick it down the road if you think it should
wait for the ffmpeg integration.

No need to indent the commit log.

probably no need to mention --enable-libvidstab here explicitly.

Unneeded empty new line.

License is GPLv2+

Unneeded new line.

However, unfortunately, it doesn't build here: it uses x86 specific gcc
flags even on ARM:

Could you fix those issues and send an updated version of the patch?
Also, make sure that it builds fine with a static only toolchain like
http://autobuild.buildroot.org/toolchains/configs/br-arm-full-static.config
and if it doesn't, make the package depends on !BR2_STATIC_LIBS (see
other packages).

I'll mark your patch as Changes Requested in our patch tracking system.

Thanks!

Thomas
