While building host-babeltrace2 asciidoc python3 module is required but
Buildroot doesn't make it available, so let's --disable-man-pages for host
as we do for target.

Babeltrace 2 is a trace manipulation toolkit.
The Babeltrace 2 project offers a library with a C API, Python 3
bindings, and a command-line tool which makes it very easy for mere
mortals to view, convert, transform, and analyze traces.
See <https://babeltrace.org/> for more details.
Babeltrace 2 is a major update of Babeltrace 1 (Buildroot package
`lttng-babeltrace`). Both projects are coinstallable. Except for the
command-line tool (named `babeltrace2`), the Babeltrace 2 project is not
backward compatible with Babeltrace 1.
I'm naming this package `babeltrace2` instead of `lttng-babeltrace2`
because, although it can read LTTng traces, the two projects are
independent. All major distributions use `babeltrace2` as the
Babeltrace 2 package's name.
I'm keeping the `lttng-babeltrace` package because, as of this date, we
still add bug and security fixes from time to time, therefore the
project is not in EOL stage. Some external, custom packages could still
depend on the Babeltrace 1 library, for example.
As with `lttng-babeltrace`, you can build and install the host version
of Babeltrace 2 for the workflow where you trace the target, download
the resulting trace (or receive it during the tracing process), and then
read and analyze it with Babeltrace 2.
If you enable the `elfutils` package (`BR2_PACKAGE_ELFUTILS`), then
support for Babeltrace 2's debugging information filter component
class is enabled.
Tested with glibc, uClibc-ng, and musl.
