    Fuzzer harnesses for sig verify and pubkey parsing
    
    These are some basic clang libfuzzer harnesses for signature
    verification and public key parsing. Some assembly (metaphorical)
    required.

commit de35c382894964a896a63ecd5607d3a3b93af75d
Author: Damien Miller <djm at mindrot.org>
Date:   Fri Sep 8 12:38:31 2017 +1000

    Give configure ability to set CFLAGS/LDFLAGS later
    
    Some CFLAGS/LDFLAGS may disrupt the configure script's operation,
    in particular santization and fuzzer options that break assumptions
    about memory and file descriptor dispositions.
    
    This adds two flags to configure --with-cflags-after and
    --with-ldflags-after that allow specifying additional compiler and
    linker options that are added to the resultant Makefiles but not
    used in the configure run itself.
    
    E.g.
    
    env CC=clang-3.9 ./configure \
      --with-cflags-after=-fsantize=address \
      --with-ldflags-after="-g -fsanitize=address"
