ok ;-)

That is a different error. I suggest to go with the AIX definition by adding
  -D_LITTLE_ENDIAN=1234 -D_BIG_ENDIAN=4321 -D_BYTE_ORDER=4321 -D__ENDIAN_DEFINED=1
as can be seen in
  https://github.com/collectd/collectd/blob/master/src/libcollectdclient/collectd/stdendian.h#L119

Also please use „make V=1“ so we can verify the compiler invocations.
I also suggest to not add all this to CC but more like
  CPPFLAGS="-D_POSIX_C_SOURCE=199506L -D_HPUX_SOURCE -DBIG_ENDIAN“
  LDFLAGS="-lpthread“

Best regards
