At this moment manylinux1 packages are providden, but in case of package build on non-x86 platforms it require to rebuild cython (and it cost time).
For now it possible to build manylinux2010 and manylinux1 automatically in manylinux2010 image (no any script changes, except image name) and separately manylinux2014 (several platforms) on CI.
Idea: build as minium aarch64 due to it popularity.
