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.
expat is required by cross for OpenOCD support, but not provided for native
builds, so replace BINUTILS_GDB_TARGET_FLAGS with BINUTILS_GDB_NATIVE_FLAGS.

A user just added RTEMS support to the GCC port (via newlib), which is
very similar to the existing newlib port but has a different tuple.
This patch allows users to override the tuples to build other targets if
they want to.
We need this to have different polarity for different platforms (Windows
vs RedHat). I don't know how to autodetect this for now, so I'm just
doing it manually.
