            Bug ID: 98806
           Summary: libphobos: Resulting executables segfault on mipsel
                    architecture
           Product: gcc
           Version: 9.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: d
          Assignee: ibuclaw at gdcproject dot org
          Reporter: ibuclaw at gdcproject dot org
  Target Milestone: ---

First reported in debian [1] and later confirmed.

The issue is that on MIPS, dynamic sections are read-only (glibc sets
DL_RO_DYN_SECTION 1), which requires special handling when getting data from
dl_phdr_info.  This is already done for RISCV, so just need to compile in the
same code for MIPS as well.
