These toolchains were built with musl-cross-make.tar.xz, which includes all the source tarballs. Run ./mcm-buildall.sh to reproduce them in the "ccc" subdirectory. See https://landley.net/toybox/faq.html#cross2 for details. Each cross-compiler.tar.xz has a cross compiler: prefix $ARCH-cross/bin/$ARCH- Each native-compiler.sqf is a loopback mountable squashfs filesystem. The file ccc.txz has all cross and native toolchains together, for all targets. Currently built from: musl 1.2.5, linux 6.8, gcc 11.2.0, binutils 2.33.1
