Issue looks like its at least partly because source build is used, aka, not wheel and then the speedups c code isnt compiled.

Environment:

• Python version: 3.7.5
• MarkupSafe version: > 1.1.1

We provide aarch64 wheels. If pip is downloading the sdist, then perhaps you need to update pip? You'll need a version that supports at least manylinux2010. https://pypi.org/project/MarkupSafe/2.0.1/#files
