Use the same interpreter to run pmdinfogen as for other build scripts. Adjust wrapper script accordingly and also don't suppress stderr from ar and pmdinfogen. Add configure-time check for elftools Python module for Unix hosts. Add pyelftools to CI configuration and build requirements for Linux and FreeBSD. Windows targets are not currently using pmdinfogen. Suppress ABI warnings about generated PMD information strings.
