I don't think the term "gdbserver" is correct here (in a traditional way).

An IDE (such as DDD, Eclipse, Lazarus, ...) is supposed to access the 
"normal" gdb via the normal line interface (pipe), while gdbserver (aka 
the "gdb stub") is supposed to be accessed via the gdb (main) program 
itself via a dedicated gdb-internal pipe.

That  is why there are two ways to make Lazarus do remote (and 
potentially cross-arch) debugging:

(A) Use gdb (compiled for the PC arch, maybe with respect to the target 
arch in order to allow disassembling etc) on the development PC and have 
it access gdbserver (compiled for the target arch) on the remote machine 
e.g. via a TCP/IP socket pipe.

(B) Have Lazarus via ssh start and access the command line of the normal 
gdb main program on the remote machine compiled for the target arch.
