Getting ELF testsuite regression on Fedora 40 x86_64 platform, not sure if it is known issue.

Following are steps to reproduce it.

Comment 1 Florian Weimer 2024-05-08 09:16:49 UTC 
This happens because libgcc_s in Fedora 40 requires the _dl_find_object@GLIBC_2.35 symbol, which is not present in glibc 2.34.

I tried to build and test glibc 2.34 on later Fedora releases (to simplify downstream development), but it doesn't quite work (even after copying libgcc_s from UBI9). Some of the tools on malloc/ have dependencies on system libraries that in turn require more recent glibc symbols.
