If its just that you can try replacing all the fenv stuff with stubs
doing nothing. You only lose some runtime warnings about special cases.
Why do you want to run numpy on such a system?
Numpy is not really intended to run on such devices.
But it is possible the debian armel port is so far I know softfloat and
numpy seems to be running fine, though it probably also emulates fenv.
