Build on aarch64 fails

[Shadow53]

My OnePlus 7 Pro is set up with an openSUSE chroot inside of Termux. Attempting to build texlab results in the following error (unrelated output trimmed away):

$ cargo install --git https://github.com/latex-lsp/texlab.git --tag v2.2.0

I can confirm this issue with a native compile. rustc 1.45.2 (d3fb005a3 2020-07-31)

Can conform this as well , seems to fail on aarch64 and armv7l (both glibc and musl)

This seems to be fixed a long time ago by https://github.com/latex-lsp/texlab/pull/298.
