Example sizes of statically-compiled (portable) toolchains

328.7M llvmbox-15.0.7+3-x86_64-linux

242.3M x86_64-linux-musl-native

169.4M x86_64-linux-musl-cross

A statically-compiled Rust toolchain would exceed these sizes by a relatively large margin

Is python actually a requirement for compiling the rust toolchain so compiling rust toolchain requires compiling python first

LLVM is a bit easier to set up in my experience. One of the most irritating things about setting up a GNU toolchain is the hard dependency on texinfo (which has been dropped in later versions I think).

In general I've found rust pretty easy to build.

Is cmake actually a requirement for compiling LLVM such that one must compile cmake before one can compile LLVM.

Compiling a statically-linked cmake is time-consuming and difficult if not infeasible.
