dev-manual: Updates to expose cross-toolchain recipes.

Browse Source 
Added a bulleted list to the "Terms" section to help define
some toolchain recipes such as gcc-cross-initial,
gcc-cross-intermediate, and so forth.

Added a cross-reference link to the term
"Cross-Development Toolchain" in the the "Working Using
Stand-alone Cross-development Toolchains" section.
This gives the reader a way to see more on the toolchain
recipes.

A collection of software development

This toolchain contains cross-compilers, linkers, and debuggers that are specific to
an architecture.
You can use the OpenEmbedded build system to build a cross-development toolchain

You can use the OpenEmbedded build system to build a

The Yocto Project ships with images that contain installers for
toolchains for supported architectures as well.

for the target.

The the final stage of the bootstrap process that
results in the cross compiler that runs on the host
and builds software for the target.
If you are replacing the cross compiler toolchain
with a custom version, this is what you must replace.

Stage 1 and 2 of the a cross compiler that runs on the
