The inline plt code emitted by gcc is incompatible with the
linker/ld.so --tls-get-addr-optimize scheme. This is the runtime
optimisation where the first call to __tls_get_addr results in
__tls_get_addr updating the tls_index pair, then the special linker
stub using that to short-circuit second and subsequent calls for a
given tls symbol. Enabled by default when the linker sees
__tls_get_addr_opt is preseent, and enabled in ld.so when DT_PPC64_OPT
has PPC64_OPT_TLS set. Note that this is distinct from link-time tls
optimisation.
PR 32387
* elf64-ppc.c (ppc64_elf_check_relocs): Disable tls_get_addr_opt
on detecting inline plt calls to __tls_get_addr.
