After the necessary dependencies installation, following commands were issued:
git clone https://github.com/ucb-bar/chipyard.git
cd chipyard
./scripts/init-submodules-no-riscv-tools.sh
The error stated below is encounter when the following command is executed:
./scripts/build-toolchains.sh riscv-tools
What is the current behavior?

Other information
May I know what is causing the issue? Any support would be helpful.
Hmm, this looks like it could be this issue: https://github.com/riscv/riscv-gnu-toolchain#troubleshooting-build-problems
If building a linux toolchain on a MacOS system, or on a Windows system using the Linux subsystem or cygwin, you must ensure that the filesystem is case-sensitive. A build on a case-insensitive filesystem will fail when building glibc because *.os and *.oS files will clobber each other during the build eventually resulting in confusing link errors.
Here is the PR that added that note: https://github.com/riscv/riscv-gnu-toolchain/pull/529
It has some links to related issues, so maybe there will be some tips in there for how to resolve the issue.
If you build entirely within WSL the build tool script works (barring other environmental shenanigans). The fact @CuriousSingularity is building on /mnt here suggests they're sharing across to Windows where the filesystem is case-insensitive which, as tymcauley has already pointed out, is problematic for the build tool.

I am using msys2, how can I set case sensitivity?
We only support Linux officially, and the conda-build flow should prevent issues like this in the future.
