[FFmpeg-devel] Patch to remove build path from tools/cl2c

[Vagrant Cascadian]

The attached patch removes build paths from the resulting binaries,
which makes it easier to verify the reproducibility of a build without
needing to know the path from which it was originally built.

I ran "make fate" with and without the patch applied, and all of the
tests that passed as of commit 3cc3f5de2afda5b8f880c0817e9d67c2dafbfe1e
still passed (fate-sws-slice-yuv422-12bit-rgb48 and
fate-sws-slice-bgr0-nv12 both failed regardless of weather the patch was
applied).

This was originally reported at https://bugs.debian.org/985187

With this change applied, the ffmpeg package in Debian should build
reproducibly:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/ffmpeg.html


Thanks for maintaining and developing ffmpeg, it is a very useful tool!
