for n32 ABI support. * Makefile.in: Regenerate. * configure.tgt (mips64*el-*-linux-gnu*,mips64*-*-linux-gnu*): Add n32 ABI emulations for these 64 bit targets. * emulparams/elf32bmipn32.sh: Expand comment. * emulparams/elf32btsmipn32.sh: New file, for traditional big endian n32 ABI. * emulparams/elf32ltsmipn32.sh: Likewise for little endian.
