[RESOURCE][TOOLCHAINS] Repo friendly Toolchains.

I've been following all the wonderful guides for building and compiling; but I've been having trouble finding the exact locations of the toolchains.
So I'd like to share my manifest for the same.
The repo tool can be used for getting all the toolchains [that I know] in one go for ease of development,
