commit 342a1a23793cb99921abeabe882adf8652ba715d
Author: Richard Levitte <levitte at openssl.org>
Date:   Wed Sep 7 20:56:20 2016 +0200

    Allow asan, msan and ubsan to be configured with shared libraries
    
    The background story is that util/shlib_wrap.sh was setting LD_PRELOAD
    or similar platform dependent variables, just in case the shared
    libraries were built with -rpath.  Unfortunately, this doesn't work
    too well with asan, msan or ubsan.
    
    So, the solution is to forbid the combination of shared libraries,
    -rpath and any of the sanity analyzers we can configure.
    
    This changes util/shlib_wrap.sh so it only contains the code that sets
    LD_PRELOAD when -rpath has been used when configuring.
