    Issue 25: Building within a sandbox environment fails
    
    When building in a sandbox environment, the build system's substitution variable,
    @LD_PRELOAD@ is confused with the environment variable LD_PRELOAD and build fails
    with an error that it cannot load ld.so.
    
    By Renaming @LD_PRELOAD@ to @LDPRELOAD@, we disambiguate the two.
