Progress!
I tried the command with the -p option (supposed to supress the progress indicator)

sudo ./gz_load test1.xsvf -v 4 -p

Now at least there are error messages:

ERROR: Data overflows allocated MAX_LEN buffer size
ERROR at or near XSVF command #62. See line #62 in the XSVF ASCII file.
ERROR: Data overflows allocated MAX_LEN buffer size
Execution Time = 0.040 seconds

So I tried to generate some more xsvf files in Xilinx Impact - to try the ID, erase and verify commands.
It turns out the utility and the connections work, it is the actual xsvf file with the configuration that is troublesome:

pi@Rosrasp-1 ~/gcc/Guzunty/src/gz_load $ sudo ./gz_load test1-id.xsvf
Guzunty loader v5.01 rev 2, portions courtesy Xilinx, Inc.
XSVF file = test1-id.xsvf
Progress indicator: ||
SUCCESS - Completed XSVF execution.
Execution Time = 0.010 seconds

Onto something: From the lenval.h file in the gz_load source folder:

The following MAX_LEN values have been tested and provide relatively
good margin for the corresponding devices:

DEVICE MAX_LEN Resulting Shift Length Max (in bits)
--------- ------- ----------------------------------------------
XC9500/XL/XV 32 256

CoolRunner/II 256 2048 - actual max 1 device = 1035 bits

Edited one line to read #define MAX_LEN 256 in lenval.h:

pi@Rosrasp-1 ~/gcc/Guzunty/src/gz_load $ make clean
rm -f lenval.o micro.o ports.o *~ lenval uart micro ports main
pi@Rosrasp-1 ~/gcc/Guzunty/src/gz_load $ make
[CC] lenval.c
[CC] micro.c
[CC] ports.c
gcc -o gz_load -Wl lenval.o micro.o ports.o -L/usr/local/lib -lbcm2835 -lrt
pi@Rosrasp-1 ~/gcc/Guzunty/src/gz_load $ sudo ./gz_load test1.xsvf
Guzunty loader v5.01 rev 2, portions courtesy Xilinx, Inc.
XSVF file = test1.xsvf
Progress indicator: |*******|
SUCCESS - Completed XSVF execution.
Execution Time = 14.260 seconds
pi@Rosrasp-1 ~/gcc/Guzunty/src/gz_load $

And the Coolrunner is configured again!

I have installed Terminal IDE on my Android tablet. Also, I configured port forwarding in my internet router for the ssh port 22 to my raspberry. Now I can pet my Raspberry from anywhere,and I can start thinking about a more serious project for a home management system involving the Pi and it's little cpld friend.

Long time since last update. Moved back to my own house, and now the raspberry has been installed in the boiler room, ready to become the central of the house.

First task is to install sendmail so that the Pi can send updates to me by email.

Oh the pain, the suffering. Don't install sendmail, it's horrid, pick ANY other MTA, NOT sendmail. My choice is postfix because it's orders of magnitude easier to configure and work with.

Kind of figured that out already. Thanks for the confirmation.
Used this guide instead: http://iqjar.com/jar/sending-emails-fro ... pberry-pi/

The first duty for the Pi will be the electronic watchdog that I always wanted but did not know how to create.

Ingredients: MP3 file. Old Kenwood amplifier. Old speakers. Infrared detector.
Now I just have to drill a hole in the cellar window for the cable to exit to the detector.
