How to blacklist a shared library to avoid it being fetched by the loader?

I'm trying to force a build internal pre-processor used for built-sources to not rely on shared libraries installed in my host machine without having to uninstall them.

Although there is a LD_PRELOAD environment variable which forces the loader (ld-linux) to fetch the specified shared libraries before anything else, I'd like to do quite the opposite, forcing the loader not to fetch the specified libraries during the setup process (kind of LD_NEVERLOAD variable).

Is there some way to do so without breaking my entire system (aka, removing such libraries)?

PS: I've renamed my system libraries to test this specific use case, but this is definitely not an elegant way of doing so.

Reading the manual pages ld(1) and ld.so(8) you might try playing with LD_LIBRARY_PATH, LD_RUNPATH and options in both manuals which are related to "rpath".
