OK, I tested graphics/libfpx on i386-current:

-stack-protector-strong indeed gets pulled in due to some non-orthodox
workarounds in files/Makefile.bsd.

g++48 accepts it just fine and the port compiles.

Is this a platform that has GCC issues, perhaps? It looks like one of those
"unfortunately series of events" that may have to be fixed in the port
and/or gcc48.
