Fix an issue with commit73934d319d("Disable .gnu.hash on MIPS targets"), <https://sourceware.org/ml/binutils/2006-07/msg00341.html>, which in turn caused a regression with commit861fb55ab5("Defer allocation of R_MIPS_REL32 GOT slots"), <https://sourceware.org/ml/binutils/2008-08/msg00096.html>, and use `mipself.em' as the extra emulation file for `mips-*-windiss' targets, removing a segmentation fault triggered as `_bfd_mips_elf_final_link' calls `htab_traverse' to process LA25 stubs with `htab->la25_stubs' being NULL. This is in turn due to `_bfd_mips_elf_init_stubs' not having been called, which is only done by `mipself.em'. No LA25 stubs are supposed to be produced for `mips-*-windiss' targets, however the internal data structures have to be initialized. ld/ * emulparams/elf32mipswindiss.sh (EXTRA_EM_FILE): Set to `mipself'.
