`System::loadLibrary("systeminfo")` should call `JVM_LoadLibrary` with 
"/usr/lib/libsysteminfo.so" argument (let the .a file exists under "/usr/lib") 
which in turn calls `os::dll_load`.    JDK-8320005 changed `os::dll_load` to 
first load the given filename; if fails, it will call `dll_load_library` with 
"/usr/lib/libsysteminfo.a".    

You can turn on `-Xlog:library` and it should print log message loading 
"/usr/lib/libsysteminfo.so"  if you have `loadLibraryOnlyIfPresent` to return 
false. If you don't see log message loading "/usr/lib/libsysteminfo.so", 
`loadLibraryOnlyIfPresent` still returns true.

Turn on "-Xlog:os" should print "attempting shared library load of 
/usr/lib/libsysteminfo.so" and "attempting shared library load of 
/usr/lib/libsysteminfo.a" log message.
