That's only true if you build a uClibc-based toolchain. If you build a
glibc- or a eglibc-based toolchain, then crosstool-NG allows you to
use NPTL.

So I'll take that you build a uClibc-based toolchain...

That has to match the way you configured uClibc in your toolchain.
Check the uClibc .config file for that.

libthread_db.so.1 is dlopen(3)ed by gdbserver, so you have to get it on
your target, in the standard libraries search path.

Also, there is a known dangling issue wrt cross-gdb + gdbserver.
See this thread:

In short, you have to get the cross-gdb *and* the gdbserver from the
same version of gdb, to be sure they know how to speak to each other.
So: either get both from crosstool-NG, or get both from buildroot.
