Hi,

Most of the targets we deal with need to be told to lift off breakpoints 
from the inferior prior to single-stepping. A few targets are able to 
just step over those breakpoints without being told so.

In the latter case, GDB assumes the target knows how to manage 
breakpoints on its own.

gdbserver does not know how to do this unless we force this mechanism 
into it, but, honestly, i don't see the point. Usually targets that know 
how to step over breakpoints do so via a more low level interface like 
the kernel. Let me know if you think otherwise.
