The first step would probably be dropping a musl-compatible (generic, not gnu-linux) libstdc++ into the test environment. > I mostly do building in KVM now to test how applications are portable > and collect the patches that will be needed when transiting to > musl-enabled system.

With that set, cross-compiling seemed fairly easy to me. Also, I often set up a chroot with musl and build under that. If you'd rather not build the whole chroot yourself, you can prepare a chroot and follow the installation notes for converting a glibc-based system, using the chroot environment instead of a full install (this works well with Debian). If you do this, make sure not to do a plain cp of the system libraries; this would mess up the sonames, since lib*.so must be symlinks to lib*.so.<version>. It also really messes with ldconfig.
