This happens because we're not checking for headers before checking
for dependencies. All the compile attempts fails and script thinks
that we need more dependencies.
With this change script will check for 'rte_config.h' availability
and produce sane error message:
# ./configure --with-dpdk=/wrong/path
...
checking for rte_config.h... no
configure: error: unable to find rte_config.h in /wrong/path
'AC_INCLUDES_DEFAULT' passed explicitly to avoid preprocessor test.
