==================================

Set compiler and options. Disable float-divide-by-zero and pointer-overflow
sanitizers when using UBSan.

    export CC=clang
    export CFLAGS="-g -fsanitize=fuzzer-no-link,address,undefined \
        -fno-sanitize=float-divide-by-zero,pointer-overflow \
        -fno-sanitize-recover=all \
        -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION"

Build libxml2 with instrumentation:

    cd /path/to/libxslt
    ./configure --without-python --with-libxml-src=/path/to/libxml2
    make
