Libc update to simplify merge. 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.

Import unmodified NetBSD libc in trunk This patch imports the unmodified current version of NetBSD libc. The NetBSD includes are in /nbsd_include, while the libc code itself is split between lib/nbsd_libc and common/lib/libc.
