Since the update of ffmpeg to 6.1.1 in commit
fa36a6375d there are
a lot of microblaze build failures.
The compilation failure is triggered by GCC Bug 68485.
We need to disable optimisations, or ffmpeg would add -O3, which would
be present after the -O0 we add, overriding it.

VSX is indeed an extension to AltiVec, so havinf VSX implies having
AltiVec [0], so we can condition he altivec support on LE ,on VSX being
available.
To be noted, however, is that ffmpeg has a configre switch dedicated to
VSX: --enable-vsx. We do not use it add support for that here, as we are
just fixing the AltiVec support. Adding VSX configure flag is left as an
excercise for a future feature addition.

mips_32 is not supported by ffmpeg and it tries to build with loongson3
SIMD support that leads to build failure due to:
/tmp/ccFO2LRa.s: Assembler messages:
/tmp/ccFO2LRa.s:15314: Error: opcode not supported on this processor: mips32 (mips32) `dmult $2,$6'
/tmp/ccFO2LRa.s:15316: Error: opcode not supported on this processor: mips32 (mips32) `dsrl $2,$2,32'
So let's --disable-asm to prevent using those unsupported opcodes for every
mips architecture according to Arnout.

opencv 2.x has seen no release since July 2018 and all buildroot
packages are already compatible with opencv3 so drop it to ease the
addition of opencv4 which is not fully backward compatible with opencv3
as "a lot of C API from OpenCV 1.x has been removed.":

Add a patch to fix build without ssse3.
Update the license hash due to various changes since August 2019 [0]:
- some files were relicensed from GPL-2.0+ to LGPL-2.1+; no impact on
the licensing information;
- clarification about the licensing when linked with external
libraries, which now requires passing --enable-version3; Buildroot
is not concerned, because it passes --disable-version3;
- various clarification about applicable licensing terms.

With Microblaze Gcc version < 8.x the build hangs due to gcc bug
85180: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180. To avoid
this problem, until now, ffmpeg could not be selected on
Microblaze. However, this problem only happens due to optimization,
and can worked around by forcing -O0.
So, when BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y, this commit:
- adds --disable-optimizations to FFMPEG_CONF_OPTS
- passes -O0 to CFLAGS in FFMPEG_CONF_ENV
Then, we remove 'depends on !BR2_microblaze' from Config.in to
re-enable the package.
Note that the comment was talking about gcc bug 71124, but this gcc
bug is a duplicate of 85180. Since all Buildroot packages now use the
reference to gcc bug 85180 and the option is named
BR2_TOOLCHAIN_HAS_GCC_BUG_85180, we use this naming as well for
ffmpeg.

The BR2_GCC_TARGET_* configuration variables are copied to
corresponding GCC_TARGET_* variables which may then be optionally
modified or overwritten by architecture specific makefiles.
All makefiles must use the new GCC_TARGET_* variables instead
of the BR2_GCC_TARGET_* versions.
