elf32bmipn32.sh was both being used by irix and also included by
elf32btsmipn32.sh, elf64bmip.sh, and elf64btsmip.sh. This patch
creates a common include file elf32bimipn32.sh.
1. rename elf32bmipn32.sh to elf32bimipn32.sh
2. change elf32bmipn32.sh to include elf32bimipn32.sh
3. have elf32btsmipn32.sh, elf64bmip.sh, and elf64btsmip.sh include
elf32bimipn32.sh
4. Include a couple changes for glibc
* emulparams/elf32bimipn32.sh: Equivalent to elf32bmipn32.sh.
* emulparams/elf32bmipn32.sh: Use only for irix.
* emulparams/elf32btsmipn32.sh: Include elf32bimipn32.sh.
(SHLIB_TEXT_START_ADDR): Unset.
* emulparams/elf64bmip.sh: Include elf32bimipn32.sh.
(LIB_PATH): Set.
* emulparams/elf64btsmip.sh: Include elf32bimipn32.sh.
