The current value

LIBFUZZER = /home/nickm/build/libfuzz/libFuzzer.a

isn't portable enough IMO.
BTW if I configure the sources (with clang 3.9.1):

CC="clang" ./configure --config-cache --enable-expensive-hardening --enable-libfuzzer

then I run during make into

$ make
make  all-am
make[1]: Entering directory '/home/tfoerste/devel/tor'
  AR       src/ext/keccak-tiny/libkeccak-tiny.a
  AR       src/trunnel/libor-trunnel.a
  CC       src/ext/trunnel/src_trunnel_libor_trunnel_testing_a-trunnel.o
clang-3.9: error: unsupported argument 'trace-pc-guard' to option 'fsanitize-coverage='

at a stable (hardened) Gentoo Linux.

I'm moving to the current upcoming milestone, so this ticket doesn't get lost. People can move it to 0.3.2 if they want.

dgoulet, what do you think about having this just do "-lFuzzer", and require that you have libFuzzer in an appropriate path if you're going to be messing around with libfuzzer support?

That's much better than me changing the path to my home directory :).
