Just a quick top-posted note: lang/gcc5 (as of /usr/ports -r416711) built fine,
unlike the lang/gcc6 noted before/below. [I happened to try lang/gcc5 with the
bootstrap configuration item disabled.]
I may try lang/gcc6-devel to see what it does.

lang/gcc6-devel (as of /usr/ports -r416711) also built fine on the rpi2. [The
test was with the bootstrap configuration item disabled.] Only lang/gcc6 seems
to have the reported problems for the rpi2. But I've not tried lang/gcc49 or
before. Nor have I tried any devel/*gcc* examples.
The rest of the below material just repeats the original evidence of the
lang/gcc6 problem. Continue reading only if you care for that detail now.
