[OpenSmalltalk/opensmalltalk-vm] Latest commit segfaults win64x64.squeak.cog.spur (#498)

Trying to load a 64-bit image, the VM segfaults in gcc3x-cointerp.c line 2809 memset(theStackMemory, 0, stackPagesBytes);

Other win64x64 targets might be affected. I tested both a custom build and bintray version: https://bintray.com/opensmalltalk/vm/download_file?file_path=squeak.cog.spur_win64x64_202005091950.zip

I have rebuild a working VM from 020c80f
(CogVM source as per VMMaker.oscog-eem.2751 - may 8)

But this one segfaults: ee89a4d
(Merge branch 'Cog' of https://github.com/OpenSmalltalk/opensmalltalk-vm into Cog - may 9)

Ah Ah!
If I revert those 3 lines from build.win64x64/common/Makefile.tools then the broken VM works again!

ifeq ($(COMPILER_TO_USE),clang)
COGDEFS:=$(COGDEFS) -mno-stack-arg-probe
endif

So the problem comes from 920248d
