    libphobos: Fix executables segfault on mipsel architecture
    
    The dynamic section on MIPS is read-only, but this was not properly
    handled in the runtime library.  The segfault only occurred for programs
    that linked to the shared libphobos library.
    
    libphobos/ChangeLog:
    
            PR d/98806
            * libdruntime/gcc/sections/elf_shared.d (MIPS_Any): Declare version
            for MIPS32 and MIPS64.
            (getDependencies): Adjust dlpi_addr on MIPS_Any.
    
    (cherry picked from commit 81f928ec8e8abf1f21c5ff008c39b5d6af78f6cb)
