libphobos: Fix executables segfault on mipsel architecture

Browse source 
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.
