RFR: 8260413: x86_32 slowdebug build fails after JDK-8259894

[Aleksey Shipilev]

$ CONF=linux-x86-server-slowdebug make clean all
...
* For target buildjdk_hotspot_variant-server_libjvm_objs_compile.o:


 4673 | jio_snprintf(output, sizeof(output), "%s:%d", CompilerPhaseTypeHelper::to_string(cpt), idx);
      | ^~~~~~~~~~~~
      | vsnprintf

 4675 | jio_snprintf(output, sizeof(output), "%s", CompilerPhaseTypeHelper::to_string(cpt));
      | ^~~~~~~~~~~~
      | vsnprintf

It is somewhat weird it only manifests on x86_32 and only in slowdebug.

Additional testing:
 - [x] Linux x86_32 slowdebug build
