What work it involves -- 
1) First gdbserver must understand the extra set of 
tracepoint remote protocol commands (or a subset of them:
tracepoint support is very subset-able).  I'm sure these
commands are documented somewhere...
2) Then gdbserver has to know how to implement a tracepoint, 
ie. to stop the child, quickly collect a well defined set of
data into a cache, then continue the child without any 
interaction with gdb.

AFAIK no one has worked on it in a while.
