As a heads-up, powerpcspe needs a similar treatment as it suffers from the same problem:

  cd build-llvm \
  CFLAGS=`dpkg-buildflags --get CFLAGS`; \
  CFLAGS="$CFLAGS `dpkg-buildflags --get CPPFLAGS`"; \
  echo $CFLAGS; \
  bin/clang++ -c $CFLAGS -std=c++11 ../lib/Fuzzer/*.cpp -IFuzzer; \
  ar ruv libFuzzer.a Fuzzer*.o
  -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2

Like x32, powerpcspe is just a variant on an existing architecture, namely powerpc but with a different ABI and hence a suffix in the GNU triplet name (full triplet name is "powerpc-linux-gnuspe").
