trace-cmd use python-config to find out which headers
and libraries should be used to link against the Python libraries.
By default, python-config returns paths that are inappropriate for
cross-compilation.

This patch replaces python-config with pkg-config as a workaround.

Fixes:

Note: I'll add python3 support latter.

v1: rework python dependency
    add host-swig dependency
    disable python support if python package is not selected

v0: initial review
