LD_PRELOAD cannot find libexec.so

On the new version of bear I'm getting the following error:

ERROR: ld.so: object '/startdir/src/bear/target/release/libexec.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

There's a modifictaion to be done in 'bear/build.rs according to:

https://github.com/rizsotto/Bear/issues/648

Or seemingly an env var might be enough: https://github.com/rizsotto/Bear/blob/master/bear/build.rs#L15
