That is my understanding of the term.

That's wrong. Just as with C, some parts of the standard
libraries may have dependencies on the OS, but the base
language itself is readily usable on "bare-metal" ...
I do it frequently.

However, there's no need to use crosstool of any flavor
to build a bare-metal toolchain. I use binutils, GCC and
newlib to build cross bare metal toolchains.

I've attached a script that I use to build C/C++ for
a mips-elf target. It's nothing fancy (it doesn't
download the pieces for you), but I think you
can get the jist of building using this script. Just
adjust the version numbers to suit your tastes. :)
