#   ant, ecj, jdk: required to build Java code
# Only ant-core-1.8.1 has fixed ant -diagnostics when xerces+xalan are not present.
# ca-certificates, perl and openssl are used for the cacerts keystore generation
# xext headers have two variants depending on version - bug #288855
# autoconf - as long as we use eautoreconf, version restrictions for bug #294918
