A few facts: - building the C library requires a proper core compiler - core compiler is issued from one of the core passes - the C library is required to build libstdc++ - newlib is only built for baremetal - in bare metal, the final compiler is issued from one of the core passes So we need to build the C library between core pass 1 and core pass 2. The only place is eithe libc_headers() or libc_start_files(). The most pertinent seems to be libc_start_files(). So we build newlib from libc_start_files(), and leave libc() empty.
