Florian mentioned that this could be related to upstream commit e0ed2fb4. Applying this and rebuilding the glibc rpms didn't reproduce the errors. We should fix this.

Replace __attribute__((visibility("protected")))
With copy relocation, address of protected data defined in the shared
library may be external. Compiler shouldn't asssume protected data will
be local. But due to
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65248
__attribute__((visibility("protected"))) doesn't work correctly, we need
to use asm (".protected xxx") instead.
* elf/ifuncdep2.c (global): Replace
__attribute__((visibility("protected"))) with
asm (".protected global").
* elf/ifuncmod1.c (global): Likewise.
* elf/ifuncmod5.c (global): Likewise.
