Because shared libraries are handled by GDB, and not by gdbserver.
Take a look at thread_db_get_thread_local_address; there's a call
to svr4_fetch_objfile_link_map in it, which gdbserver can't do
(unless we were to add ELF header support to it... yuck).
That said, I wonder if this query should be handled uniquely by
remote.c, or by GNU/Linux specific code using an xfer-partial
mechanism. I haven't thought about the details yet.
