Summary
When trying to build Ruff in Termux on Android, it fails with the error unable to find library -lgcc
First, the following message is repeated many times:
'+fpmr' is not a recognized feature for this target (ignoring feature)
To finally conclude with:
...

I've found a similar issue reported to termux about vim-clap [1],
which was resolved upstream by disabling tikv-jemallocator on Android [2].
When duplicating that resolution by also disabling tikv-jemallocator in Ruff, cargo build --release will succeed, and running cargo run -p ruff -- check /path/to/file.py --no-cache also succeeds.
I don't know if that's the best solution, or even an acceptable (I'm not familiar with the Rust nor Android ecosystem), but I can create a PR with my changes for consideration.
I know there's a pre-built termux package that I can install with pkg install ruff, but I'd like to install ruff as part of a venv, for which it needs to be able to build from source.
Steps to reproduce in Termux:
pkg install build-essential rust
git clone https://github.com/astral-sh/ruff.git
cd ruff
cargo build --release
