== Toolchains limitations

Gradle may detect toolchains incorrectly when it's running in a JVM compiled against `musl`, an https://musl.libc.org/[alternative implementation] of the C standard library.
JVMs compiled against `musl` can sometimes override the `LD_LIBRARY_PATH` environment variable to control dynamic library resolution.
