In order for a Buildroot toolchain to be usable as an external toolchain, we should copy the target gdbserver somewhere into $(HOST_DIR). In order to match what Crosstool-NG does (and therefore to match something the external toolchain logic already understands), we install gdbserver in $(HOST_DIR)/usr/<tuple>/debug-root/usr/bin/gdbserver.
