brctl: eliminate stray data object

Browse Source 
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")
