Binutils and GDB are kept in the same repository but follow seperate
relaese streams. We've been release GDB versions based on binutils
tags, but this is the wrong thing to do and has caused multiple
headaches related to our out-of-tree GDB port.
This patch splits the binutils and GDB submodules, but doesn't actually
change the versions.
This also adds a submodule pointer to the RISC-V DejaGnu port, which is
required to run the GCC test suite. The DejaGnu port only supports the
GDB simulator. A bunch of tests fail right now, but that's expected.
As we prepare binutils for upstreaming we want to start closely tracking
upstream changes. There's a riscv-binutils-gdb repository that contains
the binutils port, and I want to centralize all the development there.
This commit uses that repository instead of the patches that used to
live here, so we're less likely to lose patches.
