* recursive bump for libxkbcommon 1.7.0

Marc Baudoin reported problems with using old binary packages
with the new libkxbcommon, so force everything to 1.7.0

Log message:
*: Recursive revbump from audio/pulseaudio-17.0

Log message:
multimedia/ffmpeg*: powerpc altivec fix is not cross-only

Revbump so new _native_ powerpc builds will get this fix too.

Add a comment explaining why we do this.

Log message:
multimedia/ffmpeg5: Handle machdep.altivec on NetBSD/powerpc too.

Bump revision because this built without the change on
NetBSD/powerpc, but didn't respect machdep.altivec at runtime.

Don't build with -maltivec -mabi=altivec on powerpc.  This doesn't
disable the use of altivec; it just prevents the compiler from trying
to use altivec instructions, like vector-zero and vector-store to
zero-initialize an object on the stack, outside the parts that are
gated on runtime CPU feature detection.

Fixes ffmpeg5 on powerpc CPUs without altivec.

ffplay[2-6]: Avoid generating HTML documentation.

The HTML documentation is not installed (because it's considered
part of ffmpeg rather than part of ffplay) and I am getting failures
with unsupported charsets. Waste fewer CPU cycles.
