review request -- JDK-801106 Some tests have failed with SIGSEGV on arm-hflt on build b82

[BILL PITTORE]

  Maybe something like I did for SUPPORTS_NATIVE_CX8. This gets defined 
in globalDefinitions_<cpu>.hpp.
In this situation maybe something like:

memTracker.cpp
   bool NMT_detail_supported = PLATFORM_NMT_DETAIL_SUPPORTED;

then in globalDefinitions_<cpu>.hpp

#define PLATFORM_NMT_DETAIL_SUPPORTED {true | false} as the case may be.

Then you eliminate the need to add code to pd_initialize()
