 A recent attempt to upgrade from nodejs12 @12.15.0_0 to @12.16.0_0, and an
 attempt to (build and) install nodejs13 @13.8.0_0 failed with a similar
 error. The logs for each attempt end with errors about the presence of the
 macro `MAP_ANONYMOUS` in src/large_pages/node_large_page.cc. (I've already
 discarded the log, and am disinclined to wait the several hours it takes
 to get that far in the failed build.) Apparently this macro is undefined
 on older OSXs. I'm using Mac 10.10.5.

 I searched on that, and found [https://github.com/eclipse/omr/issues/902
 this discussion], which prompted me to create the attached patch and
 attempt the build again. With the Portfile modified to include that patch,
 both nodejs12 and nodejs13 were able to build and install.
