A quick data point: I tested a build with gcc 4.6.1, uClibc 0.9.32,
NPTL, and both iperf and dbus-daemon start fine for me:

# iperf 
Usage: iperf [-s|-c host] [options]
Try `iperf --help' for more information.
# dbus-daemon 
No configuration file specified.
dbus-daemon [--version] [--session] [--system] [--config-file=FILE] [--print-address[=DESCRIPTOR]] [--print-pid[=DESCRIPTOR]] [--fork] [--nofork] [--introspect] [--address=ADDRESS] [--systemd-activation]
# uname -a
Linux buildroot 2.6.38.8 #1 Fri Sep 30 20:24:38 UTC 2011 armv5tejl
GNU/Linux

My target optimization options is:

BR2_GCC_TARGET_TUNE="arm926ej-s"
BR2_GCC_TARGET_ARCH="armv5te"
BR2_GCC_TARGET_ABI="aapcs-linux"

Therefore, I guess that the problem might be iwmmxt related. Can you
try with "lower" optimization options ?
