Same. Are there any workarounds for this problem?

Same here. I can do git clone --recursive https://github.com/riscv-collab/riscv-gnu-toolchain and it clones (newlib included).

Ok, here is a work-around. In the directory /usr/local/Homebrew/Library/Taps/riscv-software-src/homebrew-riscv, edit the file riscv-gnu-toolchain.rb. Find the line where the below comment appears, delete the three git lines as they appear, and replace with the following:

    # need to pull in needed submodules (now that they are disabled above)
    system "git", "submodule", "update", "--init", "newlib/"
    system "git", "submodule", "update", "--depth", "1", "--init", "newlib"
    system "git", "submodule", "update", "--init", "binutils/"
    system "git", "submodule", "update", "--depth", "1", "--init", "binutils"
    system "git", "submodule", "update", "--init", "gcc/"
    system "git", "submodule", "update", "--depth", "1", "--init", "gcc"

Now I have a built binary that runs, although the brew test riscv-tools fails. Still trying to figure out why.

Here is the test result:

$ brew test riscv-tools

I'm not able to reproduce the cloning issue, but it can be tricky to deal with these sorts of issues. Building from head appears stuck in general due to #127, so until that is fixed, it will be hard to confirm other build issues.
