[PATCH 1/9] libdebugger: Move to separate library

[Sebastian Huber]

Always build remote TCP support since it depends only on the POSIX
socket API.  It works with the legacy network stack and libbsd.  Move it
to a separate libdebugger.a library to allow an easy use with libbsd via
"-ldebugger -lbsd" otherwise we would have a cyclic dependency between
libbsd. and librtemscpu.a.

Update #3419.
