Reason is that this has been commited by mistake as discussed.

This reverts commit f4f5cab9.

Reason is that this has been mistakely commited as discussed.

Recent gcc versions define __ARM_PCS or __ARM_PCS_VFP to indicate the
VFP ABI in use, and ARM RVCT defines __SOFTFP__ when using this ABI.
If none of these are defined, check $cross_prefix and $cc for the
substring "hardfloat", and finally fall back to a linker test.  This
gives the correct result in most configurations.

This macro has unconditionally used .p2align for a long time and
serves no useful purpose.

This is required on systems where the linker does not change
the permissions of an existing output file.

Some linkers fail if this flag is used when creating an executable file.
Since the flag is meaningful only for shared libraries, dropping it from
the main link flags is correct.

It's useless now that we've switched to git.

Per http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2011-January/103440.html.

This fixes demuxing of packets that do not contain a codec tag and come before the codec_id has been set.

Fixes issue 2560.

Fixes issue 2505.

This may fix a bug where quicktime files use 1/600 timebase.

like it has been done prior libavfilter.
