protoc-gen-grpc-java can't be built with gradle and protobuf 22+

I'm trying to package grpc-java 1.66.0 for Alpine Linux. I have modified `compiler/build.gradle` as follows:
```
cppCompiler.executable = 'aarch64-alpine-linux-musl-c++'
linker.executable = 'aarch64-alpine-linux-musl-c++'
```
I'm using the following steps to run the build:
```
apk add openjdk21-jre-headless protobuf-dev nss
wget https://github.com/grpc/grpc-java/archive/v1.66.0.tar.gz
tar xzf v1.66.0.tar.gz
cd grpc-java-1.66.0/compiler
export GRADLE_USER_HOME="$srcdir"/.gradle
export CXXFLAGS="--std=c++17"
export LDFLAGS="-L/usr/lib"
../gradlew --no-daemon --parallel --info java_pluginExecutable -PskipAndroid=true
```
The build seems to succeed, but linking fails with:
```

But the libraries installed by `protobuf-dev` exist:
```

```
Can anyone help me resolve this linking issue?

Inizia da compiler/build.gradle e dal task java_pluginExecutable, quindi esamina build/tmp/linkJava_pluginExecutable/options.txt e il relativo output.txt. Riproduci la build Alpine con protobuf-dev installato e determina perché il linker non individua le librerie protobuf elencate; il lavoro è completato quando l'eseguibile protoc-gen-grpc-java viene collegato correttamente con il comando documentato.

Scritto dal modello di indicizzazione a partire dal testo della issue.
