gcc checks tsan and lsan support in source file 
gcc/libsanitizer/configure.tgt, it seems only support x86_64. Then tsan 
and lsan related packages will be empty for other target.
For qemuarm project, add in local.conf:

IMAGE_INSTALL_append = " libtsan"

Then run 'bitbake core-image-minimal", it shows errors:

ERROR: core-image-minimal-1.0-r0 do_rootfs: libtsan not found in the 
feeds (qemuarm armv5te armv5e armv5t armv5 armv4t armv4 arm noarch any 
all) in /buildarea3/kkang/poky-20141111/builds/qemuarm-Aug05/tmp/deploy/rpm.
