Comment:

 Seems like the problem is with numpy, not MyPaint.

 There are no occurrences of `Dragon4` in the MyPaint source that I can
 find. Meanwhile in numpy I see in
 [https://github.com/numpy/numpy/blob/main/numpy/core/src/multiarray/dragon4.c
 dragon4.c] that it only declares `Dragon4_PrintFloat_Intel_extended128` if
 `HAVE_LDOUBLE_INTEL_EXTENDED_16_BYTES_LE` is defined. Later in dragon4.c
 it invokes `Dragon4_PrintFloat_##format` in two places, so I guess
 `HAVE_LDOUBLE_INTEL_EXTENDED_16_BYTES_LE` is false on your system yet
 `##format` has expanded to `Intel_extended128` for whatever reason. I
 don't see where `format` is defined.
