Bug#866087: clang-5.0: Hard coded location for libFuzzer

[Erik de Castro Lopo]

Package: clang-5.0
Version: 1:5.0~svn305653-1
Severity: normal

Dear Maintainer,

I've installed clang-5.0 and libfuzzer-5.0-dev. According to the LLVM docs
here:

    http://llvm.org/docs/LibFuzzer.html

I should be able to do:

    clang-5.0 -g -fsanitize=fuzzer,address fuzz-target.c-o fuzz-target

but that results in the error:

    /usr/bin/ld: cannot find /usr/lib/libLLVMFuzzer.a: No such file or directory
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

The problem seems to be that Clang has a hard-coded location for the libFuzzer
library (/usr/lib/) which does not match the actual location on Debian which is

    /usr/lib/llvm-5.0/lib/libFuzzer.a

Cheers,
Erik
