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.
