[committed] MIPS/LD: Correct `mips-*-windiss' target emulation configuration


Fix an issue with commit 73934d319dae ("Disable .gnu.hash on MIPS 
targets"), <https://sourceware.org/ml/binutils/2006-07/msg00341.html>, 
which in turn caused a regression with commit 861fb55ab50a ("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'.

Hi,

 This brings `mips-windiss' test results to:

mips-windiss  FAIL: nm --size-sort
mips-windiss  FAIL: ld-scripts/fill

being the only failures.
