debug: provide an option to copy the gdbserver to the target
When an external toolchain is used, it is very likely that it contains a pre-built version of a gdbserver that has the same version as the cross-gdb included in the external toolchain. So, we now provide an option that allows to copy this pre-built gdbserver to the target. As the location of the gdbserver in the external toolchain is not standardized, we only support the CodeSourcery and Crosstool-NG layouts for the moment. Other locations can be added later.
