That makes sense, but it's one of the differences with how BLFS has
to do things. It's also why I proposed holding-off on updating rust
until there is a reason.

When I went to bed, I thought I'd sorted it all adequately. But
when I couldn't sleep I started to consider other variations.
<sigh/>
And among those is just using the shipped llvm - with that, ALL
tests passed (and it now seems to run all the tests), with system
llvm-3.9 one test for an ARM variant failed - of course - but two
other tests failed and one test burns CPU [ all with gcc-7.1 ].
But it will probably be overkill, it's a *lot* longer on my fast
machine.

That bit is done. The rust devs are moving to using config.toml
files (actually, they had already started that in 1.16.0). In this
case, the following (and then a normal ./configure) will install
both. I haven't actually _used_ this yet, but it gave me a
usr/bin/cargo in my DESTDIR. I got the pointer from Arch after
Waqyne mentioned they seemed to be installing cargo as part of rust.
cat <<EOF > config.toml
[build]
# install cargo as well as rust
extended = true
EOF
