Bugs fixed

• GH#417: The test_feed_parser test could fail if lxml_html_clean was not installed.
  It is now skipped in that case.

• LP#2059910: The minimum CPU architecture for the Linux x86 binary wheels was set back to
  "core2", without SSE 4.2.

• If libxml2 uses iconv, the compile time version is available as etree.ICONV_COMPILED_VERSION.
