elfhacks: d_un.d_ptr is relative on mips glibc too

In GLIBC, this behavior is controlled by per-architecture definition
DL_RO_DYN_SECTION, which is only set to 1 on MIPS (according to the
comments, it's because of requirements of MIPS ABI) and RISC-V (which
seems to be a left-over of copying MIPS code, and kept because of
compatibility to older GLIBC versions).
