Subject: [PATCH] opencv3, opencv4: use openblasCompat

without master's fix in #83888, opencv3 & opencv4 end up with an 8-byte
openblas, which it does work with. however this causes the python
bindings to also end up with an 8-byte openblas, which numpy doesn't work
with. force 4-byte openblas for opencv.
