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.
