/* Build xsdt table */
it replaces error-prone pointer arithmetic for build_header() API, with 2 calls to start and finish table creation, which hides offests magic from API user. While at it switch to build_append_int_noprefix() to build entries to other tables (which also removes some manual offset calculations).
