With the current binutils, glibc failed to build on ia64 checking for -z relro option... no configure: error: linker with -z relro support required ia64 linker never supported -z relro. The current binutils removes "-z relro" from "ld --help" output, which leads to configure time failure.
Not only does this not belong here, it also is no issue anymore for quite sometime. Do not ever again report build problems here.
