I tried again with the following steps. Bit I still didn't reproduced the 
error. Is there anything I missed?

$ grep clang conf/local.conf
TOOLCHAIN = "clang"
$ grep clang conf/bblayers.conf
  /dev/common/home/leimh/community/meta-clang \
$ bitbake libbsd
Build Configuration:
BB_VERSION           = "2.7.3"
BUILD_SYS            = "x86_64-linux"
NATIVELSBSTRING      = "universal"
TARGET_SYS           = "i686-poky-linux"
MACHINE              = "qemux86"
DISTRO               = "poky"
DISTRO_VERSION       = "4.3+snapshot-08d0544be3e1881b623f18931631e412a9a0158d"
TUNE_FEATURES        = "m32 core2"
TARGET_FPU           = ""
meta
meta-poky
meta-yocto-bsp       = "master:08d0544be3e1881b623f18931631e412a9a0158d"
meta-clang           = "master:81e5f4eef93b5e1d6507daaf74fce28a2ccd7cf7"
......
