There are some references to bare metal (i.e. without OS) support, especially some options to build a libc with DPDK. As there are currently no such support, it can be removed. Some comments are cleaned in the same time.
Thanks to David for having done most of this effort: config: no more bare metal environment mk: no more bare metal environment eal: no more bare metal environment app: no more bare metal environment examples: no more bare metal environment -- Thomas
