Interesting, this looks simpler than what I have done.

swig is definitely available, in package/swig/.

No, Python support is optional in trace-cmd. We should keep optional,
by doing:
ifeq ($(BR2_PACKAGE_PYTHON),)
TRACE_CMD_MAKE_FLAGS += -NO_PYTHON=1
else
TRACE_CMD_DEPENDENCIES += python
endif

No, this is wrong. The pkg-config you're using is not the target
pkg-config, but the host pkg-config. There is no need to add a
Config.in dependency for that.

Python dependency should be optional. The pkg-config dependency should
be on host-pkg-config.
See also the patch set I had posted to fix the same issue (in a
different way, which required changing python2 and python3 config
scripts):
