glibc: Fix ld.so / prelink interface for ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA
A bug in glibc 2.22's ld.so interface for the prelink support causes
the displayed values to be incorrect. The included path fixes this
issue.
Clear ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA 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:
where ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA has a conflict with
RTYPE_CLASS_TLS.
Since prelink doesn't use ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA, we
should clear the ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA bit when the
DL_DEBUG_PRELINK bit is set.
