The sourcery toolchain recipe pulls files from a codesourcery / mentor
graphics Sourcery G++ toolchain installed at the EXTERNAL_TOOLCHAIN path.
That SRC_URI will not do anything, and it expects the compiler to be
available at parse time. Basically, the tcmode and recipe for sourcery is
designed for a particular toolchain, not any random one, and is not
structured at this time to allow extraction of a toolchain binary tarball.
You'd have to customize / create your own based on the existing bits, using
them as examples.
