First, there is no problem with pthreads. On GNU/Linux systems there is
no libpthreads, the feature is enabled with the -pthread compiler
option. The configure script is correctly reporting that there is no
libptheads library on your system.

Octave is not yet compatible with SUNDIALS version 3, so the warning
messages are explaining that and correctly disabling all SUNDIALS
features. If you want to help ensure that Octave 5 will be compatible
with SUNDIALS 3, you can participate in the bug report
