aarch64 support

[srounce]

I recently tried building distributions for aarch64, but the code seems quite specific to x86. Does a port exist/is there one planned for aarch64?

I am unaware of any plans or efforts to port distributions to aarch64. However, the cython implementations should be architecture independent. Distributions ships with three implementations: python, cython, and c++. Probably the first step to supporting aarch64 would be to disable c++ for aarch64 so at least the cython implementation could be built.
