build alf-clang-fast failed

[junyu chen]

When I input:

sudo make

then:

[*] Checking for working 'llvm-config'...

[*] Checking for working 'clang'...

[*] Checking for '../afl-showmap'...

[+] All set and ready to build.

[*] Building 32-bit variant of the runtime (-m32)... failed (that's fine)

[*] Testing the CC wrapper and instrumentation output...

unset AFL_USE_ASAN AFL_USE_MSAN AFL_INST_RATIO; AFL_QUIET=1 AFL_PATH=. AFL_CC=clang ../afl-clang-fast -O3 -funroll-loops -Wall -D_FORTIFY_SOURCE=2 -g -Wno-pointer-sign -DAFL_PATH=\"/usr/local/lib/afl\" -DBIN_PATH=\"/usr/local/bin\" -DVERSION=\"2.52b\"  ../test-instr.c -o test-instr 

echo 0 | ../afl-showmap -m none -q -o .test-instr0 ./test-instr

echo 1 | ../afl-showmap -m none -q -o .test-instr1 ./test-instr

Oops, the instrumentation does not seem to be behaving correctly!

Please ping <lca...@google.com> to troubleshoot the issue.
