sage-9.6: "Unhandled SIGILL: An Illegal Instruction Occurred"

[William Stein]

Hi,

As with sage-9.4 (?), but *NOT* with sage-9.5, now that sage-9.6 is
out I updated cocalc-docker to use it, and immediately I'm
getting complaints from users that see "Unhandled SIGILL: An Illegal
Instruction Occurred" when running Sage. I've changed
nothing about how Sage is built, i.e., using this little script:

https://github.com/sagemathinc/cocalc-docker/blob/master/scripts/install_sage.sh

This does set `export SAGE_FAT_BINARY="yes"`, so I guess
SAGE_FAT_BINARY is broken, yet again?

I'm just reverting cocalc-docker to sage-9.5 for now and updated the
release tour with a note about that.

The SageMath project does not make binaries any more. 

It's in the hands of binary-providing downstream developers to contribute to the maintenance of SAGE_FAT_BINARY.
