Bumping libc files for unsupported architectures, to simplify merging. A bunch of small fixes: * in libutil update * the macro in endian.h * some undefined types due to clear separation from host. * Fix a warning for cdbr.c Some modification which were required for the new build system: * inclusion path for const.h in sconst, still hacky * Removed default malloc.c which conflicts on some occasions.
