Toolchain: Move GDB build to a separate script
Target GDB is only used for debugging the kernel, which is not relevant
to most people. Starting with 924758c6f8
, GDB would always be built
as part of the toolchain if the user didn't have it installed. This is
unnecessary.
This commit adds a separate script for building GDB, which the user
needs to explicitly invoke. A message is added to Meta/debug-kernel.sh
which alerts the user to this fact.
