honggfuzz assumes that clang can implement -fblocks / -lBlocksRuntime. Either Gentoo's compiler-rt needs to grow -fblocks support (filed bug #729268) or we can fail in pkg_pretend() at CC=clang and ask users to use gcc.

On gcc it uses __attribute__((cleanup(. On clang it uses -fblocks. Gentoo's sys-libs/compiler-rt does not provide runtime support library for -fblocks on clang making them effectively unusable. Fail at pkg_pretend() for now.
