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.
