Subject: gdb: install gdbserver into the SDK
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=483fdd6bb73492979f67b6b6bc68e6e2ad3c89fd;p=buildroot.git

gdb: install gdbserver into the SDK

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.
