## What it is
A makefile-based build system for producing musl libc-targeting GCC cross compilers. It automates downloading, patching, and building GCC, binutils, and musl into relocatable cross toolchains for many architectures.

## Use cases
- build a cross compiler for arm or aarch64 linux musl targets
- compile embedded linux software against musl libc
- create relocatable gcc toolchains without hardcoded paths
- build cross compilers for riscv64 or mips targets
- set up a musl-based toolchain for static linking

## When to choose
- you need musl-targeting cross compilers for embedded or minimal Linux systems
- you want a simple make-driven toolchain build without heavy frameworks like crosstool-ng
- you need multiple target architectures from one source tree

## When to avoid
- you need a glibc-targeting toolchain
- you want prebuilt binaries rather than building from source
- you need Clang/LLVM instead of GCC

## Facets
- artifact type: cli-tool
- maturity: active
- function: build-tool, compiler, developer-tools
- domain: developer-tools, compilers, embedded-systems, operating-systems
- platform: cli, cross-platform
- tags: musl, cross-compiler, gcc, binutils, toolchain, makefile, embedded-linux, linux, macos
