This measn bazel could load stale and incorrect libraries from other build configs before it tries the ones in the install directory. We want our binaries to use the install directory lib path first and foremost. Ideally if our install binaries could only use the RPATH from install directory that would be best. However, since we want bazel to still make some binaries runnable in place, we need to do post link modification of the ELF header, either via patchelf, chrpath, or relinking (resource expensive).
