* qatar/master:
  configure: Don't use symlinks for creating the out of tree makefile
Merged-by: Michael Niedermayer <michaelni@gmx.at>

On some platforms (such as msys), symlinks are (poorly) emulated
by simply creating a copy of the file.

This means that when building out of tree, the build tree gets
a copy of the original makefile, which can lead to unintuitive
build errors when the original makefile gets updated later.

Instead simply create a stub makefile which includes the real
one.

lls1 taken from ff130d73

This is incompatible with libavcodec version
55.18.100 to 55.43.100 except 55.39.101
This incompatibility is caused by these libavcodec versions depending on
a libavutil 52 which is ABI incompatible with the previous ABI 52

you can avoid this incompatibility by upgrading your libavcodec so it
does no longer depend on the invalid ABI

Changes to ffv1 are more redone than merged due to them being based on
an ancient codebase and a good part of that having being done already
as well.
