It works for me in a armhf pbuilder chroot driven via qemu-user-static
on an amd64 host.
Trying to reproduce on abel.d.o, a real armhf porterbox:
* install in the chroot:
pocl-opencl-icd libpocl2-dbgsym libllvm10-dbgsym libclblas2-dbgsym
libgpuarray3-dbgsym libc6-dbg python3-nose python3-pygpu-dbg python3-scipy
libclblas-dev gdb
$ ulimit -c unlimited
$ DEVICE=opencl0:0 python3.9 -m nose -v pygpu.tests.test_blas
*** Testing for pthread-0x584
pygpu.tests.test_blas.test_dot(1, 'float32', True, True, True, False) ...
