[Buildroot] [PATCH 1/2] package/x264: disable asm on i386

[Buildroot] [PATCH 1/2] package/x264: disable asm on i386

[Bernd Kuhls]

Fixes build errors

In function 'x264_predictor_clip_mmx2',
    inlined from 'x264_8_me_search_ref' at encoder/me.c:231:30:
./common/osdep.h:455:13: error: 'asm' operand has impossible constraints
 or there are not enough registers
  455 | #define asm __asm__

Fixes:
https://autobuild.buildroot.net/results/3db/3dbc13972fe0c31584cbc9d9f928ea0d13a1ad4d/

The oldest build error of this kind dates back to 2022 with gcc 10:
https://autobuild.buildroot.net/results/080/08011e939f9d2ed949392656d744c53b1bb07117/
so a backport to LTS branches should be considered.

Is this a gcc bug, or an x264 issue?
