## Description

Musl-cross-make is a build system that automatically downloads, patches, and compiles source components to generate relocatable cross-compilation toolchains targeting the musl C library. It functions as an automated build environment for creating custom cross-compilers and standard library toolchains for alternative target architectures.

The system orchestrates the sequential downloading, patching, configuring, and compiling of multi-component toolchains, applying distribution-specific bug fixes and architecture patches directly to extracted source trees. It downloads required upstream source archives and validates their integrity using cryptographic hash checks before any build step executes, constructing dependencies in strict dependency order by bootstrapping core compilers, headers, and standard libraries iteratively.

The build process generates self-contained toolchain binaries free of hard-coded absolute host paths by enforcing relative path bindings during linking. Customization is handled through a configuration file specifying target tuples and build parameters.
