Found it!
[By default, this toolchain does not build static binaries. If you want to use
the toolchain to build these types of libraries, you need to be sure your image
has the appropriate static development libraries. Use the IMAGE_INSTALL
variable inside your local.conf file to install the appropriate library
packages. Following is an example using eglibc static development libraries:
IMAGE_INSTALL_append = " eglibc-staticdev"]
