[BusyBox] strange problem with BBinit and root=

Right.  Except seemingly in the root=/dev/ram0 case.  I actually prefer
that behavior over busybox grabbing the init= arg: I'm using busybox in
an initrd before passing control to the real (no-offense) init.  I like
how busybox calls its own init (/linuxrc) regardless, so that the real
init can use the init= arg.

I've done an additional test and enabled BB_INIT.  When I pass
'root=/dev/ram0', busybox calls init as 'init' instead of '/linuxrc',
which explains why it would bail out with usage info when BB_INIT is
disabled.
Why does busybox single out 'root=/dev/ram0' and then ignore
BB_FEATURE_LINUXRC?  Dunno....I'll start looking into source.
