Almost. It passes it to the compiler used for invoking the linker,
which then munges it and DTRT.

I don't think so. But I think the right way is to simply add $(CFLAGS)
to the linker command line. That's the usual way to use it, right? And
omitting it in the linking rule in mini-gmp/tests/Makefile is a bug.
Since CFLAGS includes -Iblah it seemed like a uglier choice.

I noticed one of those failures, and it was't trivially reproducible on
x86_64. Needs some investigation.
It seems "trivially" reproducible on ppc64 though, both real metal
versions and fake ones like ppceb-debv8 (and ppcel-debv8).
The first failure was also a bit interesting, an internal compiler error
with gcc-6.

That's the LD_LIBRARY_PATH bug, I think.

Begs for a proper gcc bug report, I guess. I fail to log in to sky, via
nshell, at the moment ("ssh -p 2222 localhost" on shell fails with
connection refused). And this failure was on the non-virtualized host
sky, right, not on one of the vms?
I've updated the instructions and added an alias in ssh_config. (The
port number had changed with the update of the tunneling mechanism.
Sorry about that!)
Indeed sky itself.
