Merge of r4866, r4867: configure fixes.

*) Configure: help updated to list upstream keepalive and least_conn.
   Patch by Joshua Zhu.

*) Configure: additional test for ExtUtils::Embed perl module presence.
   Now perl configure will correctly fail if ExtUtils::Embed perl module
   is not present in the system (found on Amazon Linux AMI, as of
   release 2012.03).
