automake: handle expat version pre 2.1
Commit aec20d66d9d13e0acd6a7199b63e1383e1e9900a (automake: properly handle non-default expat installation), assumed that up-to date distributions use a recent version of expat that handles security vunerabilities CVE-2012-1147 and CVE-2012-1148. Seems like this is not always the case and they prefer to backport only the fix, rather than use the updated library. This commit adds a default case -lexpat whenever expat is not found, while properly handling expat.pc if present.
