static linking brotli

Nobody has claimed this yet.

Hi, I'm trying to static link a rust program against fontique, but I'm getting the follow error:

```
= note: /usr/lib/gcc/x86_64-alpine-linux-musl/15.2.0/../../../../x86_64-alpine-linux-musl/bin/ld: /tmp/target/x86_64-unknown-linux-musl/debug/deps/libfontique-2c7c87f3c48b4c83.rlib(src_sfnt_sfnt.c.o): in function `sfnt_init_face':
sfnt.c:(.text+0xbe5c): undefined reference to `BrotliDecoderDecompress'
collect2: error: ld returned 1 exit status

= note: some `extern` functions couldn't be found; some native libraries may need to be installed or have their path specified
= note: use the `-l` flag to specify native libraries to link
= note: use the `cargo:rustc-link-lib` directive to specify the native libraries to link with Cargo (see https://doc.rust-lang.org/cargo/reference/build-scripts.html#rustc-link-lib)
```

I have declared brotli, and other static libs, on RUSTFLAGS, but seems to not find it anyway (also have all -dev packages, and the brotli .a file is on the same location of the other ones:
`export RUSTFLAGS="-C target-feature=+crt-static -C link-self-contained=yes -L native=/usr/lib -l static=bz2 -l static=png
-l static=xml2 -l static=fontconfig -l static=freetype -l static=expat -l static=z -l static=brotlicommon -l static=brotlidec"`
(-lbrotlicommon and -lbrotlidec appears on the cc command, already tried adding brotlidec with no luck)

Something obvious I'm missing here? I'm trying to build on alpine (tested v3.23.3 and edge).
Thanks!

Start by reproducing the static Rust build on Alpine Linux using the reported RUSTFLAGS and inspect how fontique links its native Brotli dependencies. Confirm which Brotli libraries are required and whether the build completes without undefined references; the issue mentions no repository files or tests to inspect.
