test_edge_intersects failed

Description 

Test: test_edge_intersects ...FAILED
  1. cu_geodetic.c:684 - rv & PIR_INTERSECTS

This is only failing in my 32 bits installation(Archlinux32): GCC: gcc version 8.2.1 20181127 (GCC) GEOS: 3.7.1

I'll try to bisect what caused it.

First failing commit: svn-trunk~11 (svn r17137, git 4536670dd) introduced in #4290

The configure used: ./configure CC=gcc CFLAGS=""

If I use clang (./configure CC=clang CFLAGS="") it doesn't fail, so it looks like a precision issue related to the tolerance (sufficiently curved).

r17166 fixes it for me, thanks!. I think we can back port it as with the other fixes.
