Describe the issue:

Build failures of silx on debian logs point to a problem with numpy.nanmin() for float64 on little endian MIPS platforms.

Reproduce the code example:

import numpy
data = numpy.array((float('nan'), 1.0), dtype='float64')
minimum = numpy.nanmin(data)
print(f"minimum={minimum}")
assert minimum == 1.0

Error message:

minimum=nan
Traceback (most recent call last):
  File "/tmp/testcase.py", line 6, in <module>
    assert minimum == 1.0
           ^^^^^^^^^^^^^^
AssertionError

None

Context for the issue:

This is a fundamental bug in a data type, breaking higher level verification tests in other packages.
