I've been meaning to make it work with NPTL and not found the time...
However, it will take more than making it load to make it work.  I
expect that it will also require an extension to the remote protocol to
query the thread base address.

ps_get_thread_area in LinuxThreads was only called by functions that
gdbserver did not use.  If it's necessary for LinuxThreads - it appears
to be - then you'll have to supply a working version.  This will
require describing register sets in gdbserver, which it already can do
on some platforms (see the code that uses PTRACE_GETREGS).
