You do
sudo apt-get install mingw-w64
which should pull in the compiler and binutils. (see package page here:
http://packages.ubuntu.com/saucy/mingw-w64)
Then you call the prefixed tools:
i686-w64-mingw32-*
x86_64-w64-mingw32-*
I would suggest using a distribution which has a large amount of MinGW-w64
3rd party libraries so you can benefit from those extensive packaging
efforts and not have to build everything yourself.
Examples are (in alphabetical order): Arch, Fedora, and OpenSuse. For Arch,
the toolchain is in the binary repos, and a ton of libraries are available
in the AUR.

Yes, you are correct. I'm reinventing the wheel I reinvented. I'm currently
hoping to wrap that up as is, because there are a few limitations of the
current design, which push me in the direction of a makepkg-style build
which is not really what I was going for. Anyways, I'll be able to build a
bunch of toolchains with the strike of a button again, and better than
before!
If you can't wait, the current state should be able to build you GCC 4.6.*,
4.7.*, and 4.8.* (all with posix threads in libgcc), but I'm still missing
some make patches (and perhaps a GCC 4.8 patch too) to make things work
flawlessly.
Just run:
./cross_build.sh <GCC version>
It will determine if you have a bunch of tools installed (including python,
which will be needed for LLVM/Clang unless I'm so not-up-to-date this
requirement is no longer current), and then start downloading and building
first cross-compilers, then the native ones. It builds dw2, seh, and sjlj
variants where applicable.
There's still some rough edges I need to work out though, so don't expect
no problems ;-) I'm planning to add a Cygwin cross-compiler to the list
once I figure out how that is supposed to work.

I would say yes, it's just a script you need to call.

I believe so.

They merged with the MinGW-w64 project itself and provide official builds:

Note the installer is currently broken IIRC, but you can find the new
toolchain zips here:

Have fun!
