Subject: brctl: eliminate stray data object brctl: use constant fd to reduce
 parameter passing runsvdir: do not use data/bss od: reuse bb_argv_dash last:
 do not go into endless loop on read error mount: make it not fail
 scripts/find_bad_common_bufsiz check dc: add INIT_G() (no-op for dc, but we
 want uniform usage of "G trick")
