So a fully open source toolchain will be to use xc32 open source toolchain and then ported another library (eg: newlib or uclibc or things like that) to the open source toolchain. I doubt that there will be many audiences now that xc32 works under Linux and Mac OS X, albeit will less optimization. But even if you build another library, the optimization may not be good as the xc32 libraries (some of them are from proprietary sources -- eg: MIPS).
