[Buildroot] [PATCH] toolchain-external: fix gdbserver copying for ARC GNU tools

Historically in pre-built ARC GNU tools gdbserver is located in
top-level "target-bin" folder.

Because of that fact if BR2_TOOLCHAIN_EXTERNAL_GDB_SERVER_COPY is
selected Buildroot won't find gdbserver (it looks within
SYSROOT/ARCH_SYSROOT folder).

Simplest solution is to use TOOLCHAIN_EXTERNAL_FIXUP_CMDS where copy
everything from "target-bin" foler into SYSROOT/usr/bin.

Reason to copy everything from "target-bin" is to enable possibility in
the future to copy more pre-built target binaries onto target.
