  -----------
  Fix library detection (multilib support and Python)

Probe in multilib directories (lib32 or lib64), which fixes the detection
of OpenSSL 3.0.0 library.

Use the sysconfig module when available for Python.  The
distutils.sysconfig module has been deprecated in Python 3.10.

Taken from rra-c-util.

  Log Message:
  -----------
  Request posix_prefix paths from Python sysconfig

When using the Python sysconfig module to determine paths,
explicitly request the posix_prefix scheme.  This is the default
in current versions of Python, but in Python 2.7 as packaged in
Debian buster, the default scheme is posix_local.  This breaks
determination of the include path for Python.h, since it instead
returns the include path used for locally-installed modules.

Explicitly requesting the posix_prefix scheme avoids this problem.
