We should backport this commit to provide a non-inheriting version of LD_PRELOAD:

elf: Implement --preload option for the dynamic linker
The upstream commit comes with a test case.
release/2.30/master - Not required.
release/2.29/master - Not required.
release/2.28/master - Not required.
Not putting --preload change on 2.28 or 2.28 because it's an interface change. It's downstream only. We want it in RHEL to help with testing and that could use --preload instead of an env var LD_PRELOAD.
Please backport patch to Fedora (if required):
Skip the F29 backport.
Verified with elf/tst-rtld-preload glibc test case.
