[uClibc]Using uClibc and busybox in mips arch.

[ljw]

Hi all,

I am trying to using busybox and uClibc in IDT32334 board(mips-based).
I built the root filesystem with busybox-0.60.3 and uClibc (current cvs
tree,
configured as mipsel) and found following messages at boot-up(DL_DEBUG
enabled in ldso)

It should be running /sbin/init(which is busybox of course) now, but
the system stoped here but serial console still can echo, so it seems
system still have some activities. I am confused here why it would call
pthread related functions. I don't see any pthread reference in busybox
binary.

Please give me some advice or hints. Thanks.
