"window-resize.sh" from "cli-tests" (zstd-1.5.4) fail on 32-bit targets.

Describe the bug

It looks like "window-resize.sh" doesn't work on 32-bit architectures due to lack of memory?

FAIL: compression/window-resize.sh
FAIL: compression/window-resize.sh.check_exit
Exit code mismatch! Expected 0 but got 1
FAIL: compression/window-resize.sh.check_stdout
stdout does not match!

To Reproduce
I got this issue when building for "i586" and "armh" targets (both 32-bit) for a linux distro, don't know if I can easily reproduce this.

The problem seems to be that window-resize.sh invokes zstd with the --long=31 option which is not valid on 32-bit architectures, and zstd complains about that.

zstd: error 11 : Parameter is out of bound

I have not tested whether changing the option to "long=30" lets the test succeed, but I expect it will.

[ilyakurdyukov]

Well actually it's easy to reproduce:

make CFLAGS="-O2 -m32"
make -C tests test-cli-tests CFLAGS="-O2 -m32"

For example, on Ubuntu with "gcc-multilib" installed.

"window-resize.sh" stderr:

zstd: error 11 : Parameter is out of bound

You're right, the test passes with "--long=30".
