DynamicLibraryBundle*: Allow DynamicLibraryBundleInfo impl. to designate a thread to load native libraries. (Fix Bug 566)

Due to requirements of native libraries using tls_model("global-dynamic")
a thread can be designated to load the 'tool' native libraries.

In case the tool lib uses tls_model("global-dynamic"),
an implementation shall try to let the early most thread load it.

For example, AWT-EDT shall load Mesa8 (Ubuntu-TLS) libGL.so.1
