[Vm-dev] nuSqueak source

[Yoshiki Ohshima]

For the /build.linuxARMv6/squeak.cog.spur/build.debug  case, a hack I did
was like this:

diff --git a/platforms/unix/vm/sqPlatformSpecific.h
b/platforms/unix/vm/sqPlatformSpecific.h

index 268593673..bfb57257b 100644

and this produced a runnable VM on Raspberry Pi4
