package/gdb: disable gdbserver if full gdb is enabled for ARC

With recent update of ARC toolchain to arc-2019.09-eng/rc1 versions
GDB package builds started to fail in autobuilder:

 http://autobuild.buildroot.net/results/bc5/bc52d0012944e15dee30a6e00a92f23c87d0dfda//

This error is caused by 73cc72729a18 ("Move gnulib to top level")
commit in binutils-gdb master branch and appears in ARC case because
arc-2019.09 GDB is based on binutils-gdb master branch and includes
this commit.

          Build the gdbserver stub to run on the target.
          A full gdb is needed to debug the progam.
