ODP_{BIG,LITTLE}_ENDIAN_BITFIELD were always defined, regardless the
value of system's __BIG_ENDIAN_BITFIELD and __LITTLE_ENDIAN_BITFIELD.
As a result, 'odph_tcphdr_t' bitfields in odph_tcp.h were always
arranged as big-endian.
This lead to incorrect parsing in linux-generic's 'parse_tcp' for
little endian systems, which resulted in packet's 'tcp_err' being set.
Fixed by defining ODP_BIG_ENDIAN_BITFIELD or ODP_LITTLE_ENDIAN_BITFIELD
conditionally per system's bitfield endianess.
