Keep only ELF_RTYPE_CLASS_{PLT|COPY} bits for prelink
prelink runs ld.so with the environment variable LD_TRACE_PRELINKING
set to dump the relocation type class from _dl_debug_bindings. prelink
has the following relocation type classes:
#define RTYPE_CLASS_VALID 8
#define RTYPE_CLASS_PLT (8|1)
#define RTYPE_CLASS_COPY (8|2)
#define RTYPE_CLASS_TLS (8|4)
where ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA has a conflict with
RTYPE_CLASS_TLS.
Since prelink only uses ELF_RTYPE_CLASS_PLT and ELF_RTYPE_CLASS_COPY
bits, we should clear the other bits when the DL_DEBUG_PRELINK bit is
set.
[BZ #19178]
* elf/dl-lookup.c (RTYPE_CLASS_VALID): New.
(RTYPE_CLASS_PLT): Likewise.
(RTYPE_CLASS_COPY): Likewise.
(RTYPE_CLASS_TLS): Likewise.
(_dl_debug_bindings): Use RTYPE_CLASS_TLS and RTYPE_CLASS_VALID
to set relocation type class for DL_DEBUG_PRELINK. Keep only
ELF_RTYPE_CLASS_PLT and ELF_RTYPE_CLASS_COPY bits for
DL_DEBUG_PRELINK.
