This prevents breaking (non asm) striping in that case

This more closely matches the actual use, also we use plain
strip without these flags for striping

* commit '0673ede9':
  configure: add strip flags checks
Merged-by: Michael Niedermayer <michaelni@gmx.at>

Launch option is defined in the Feed section.

Spotted-by: lazy ubitux

Should be redundant now that the option is documented.

The section shows only a limited use case, contains only redundant
information, and various mysterious mentions about things which don't
work correctly.

Mentioning build options, or bugs, or mysterious limitations should not
be done in the manual.

Fixes out of array accesses and integer overflows.

This will check if -wN '..@*' is available and fall back on -x if not;
when none are available, do not run strip at all to prevent removing
functions that might be actually needed.

This is required to build with FFmpeg compilation options.

  h264_refs: make sure not to write over the bounds of the default ref list

Conflicts:
	libavcodec/h264_refs.c

This condition should be impossible and was checked for by asserts.
the asserts are moved up in this merge to gurantee that no out of array
access can happen even if the state is "impossible".
Also if such impossible states could somehow be created, that should
be dealt with and not silently ignored.

"Bad secondary effect i just noticed: Every time version.h is changed
 (git pull for example), anything that includes config.h will be
 recompiled. And that means pretty much every single file in the tree.
