I think that is now in the top-level directory.

Is the verbosity helpful ?

I'm happy to go with the defaults, but I forget what they are.
In the early days of trying to build rustc, playing with the nmber
of codegen-units didn't seem to make any real difference.

Rust will use the number of available CPUs, unless you limit it
with taskset (both 1.22.1 and 1.23.0 use a recent enough version of
the num_cpus cargo crate to work with that).
Hmm, you are using python2 ? Maybe I should try that instead of
python3.

Umm, I think you had already build the same version and had the
correct cargo files in ~/.cargo ?

There is a lot of the proverbial brown-stuff installed, including
source files in /usr/lib.
Thanks for the comments. At the moment I've got 4 cores allocated
to building 1.22.1, before I see what happens when the big guy tries
to DESTDIR it. If that works, I'll measure it in case it gets used.
I know 1.22.1 is good enough for firefox for the moment, but I don't
know if it is good enough for librsvg.
Will try building 1.23.0 with python2, in case it's a series of
Python issues. The problem is that the issues mostly surfaced after
doing several builds of rustc, so one good build won't be
definitive.
