I very much welcome this effort; I myself have tried to create a port
for it, but it required a whole lot of hacks (AFL is intertwined with
internals of GCC, which I failed to make work); I ended up needing
to rewrite it's assembly filters in a fairly hackish way... Can't
remember precisely what the problem was though.

I don't know what this part is supposed to do:
# Workaround to make sure clang isn't confused for gcc
CC=${COMPILER_TYPE}
... but it seems to set CC to empty string on my machine; and I
get a whole bunch of this as the result:
--version: not found
make: "/usr/ports/Mk/Uses/compiler.mk" line 66: warning:
" --version" returned non-zero status
I also get this:

Missing GCC dependency?
(This is all on 10.0-RELEASE amd64).
