I see them in ./lib/gcc/epiphany-elf/5.0.0/crti.o as
"init" and "fini".

Look at your build log and see where they came from. If GCC
is automatically prepending _ to the name from C, then the
name in the crti.o needs to be different. This is IMO a bug
in GCC. They have names accessible from C on all other
architectures.

File a GCC PR and let the Ephiphany guys know. If they
are in Bugzilla, cc them. Add me as well.

But for now, do what you have to to keep moving and
ignore C++.
