Comment (by mascguy):

 From what I can see, it looks like aggressive optimization - via `-O3` -
 is being used. (While base is adding our default of `-Os`, a subsequent
 `-O3` is being added from somewhere else. It's not being specified by the
 portfile, so presumably it's coming from the Makefile, and/or CMake?)

 Using `-O1` might help, both in terms of memory consumption, as well as
 compilation time. Hard to say without testing, but it can't hurt!
