Why don't you guys (as core? or individual developer?) post
an announcement that mentions benefit of -fno-common and
ask Tier II users to fix possible fallout, before putting
random MD fixes that would cause annoying silent hangs?

For sparc, the correct place seems in sparc/autoconf.c:bootstrap().
For sun2 it's sun2/locore2.c:_bootstrap().
Most other m68k ports foo_init() for pre-main initialization.
