macOS toolchain build failing

See https://github.com/athenavm/rustc-rv32e-toolchain/actions/runs/9433633098/job/25984776025. Probably related to #1 (comment).

It looks like this is happening due to #1 (comment), which for some reason isn't macOS friendly.

Here's what I get when compiling without the compiler_builtins patch, looks like the same error originally encountered in #1.

   Compiling compiler_builtins v0.1.108
The following warnings were emitted during compilation:

warning: compiler_builtins@0.1.108: clang: warning: argument unused during compilation: '-march=rv32em' [-Wunused-command-line-argument]

error: failed to run custom build command for `compiler_builtins v0.1.108`

Caused by:
