MIPS patch: make -mel=-EL and -meb=-EB

MIPS patch: make -mel=-EL and -meb=-EB

[Richard Sandiford]

This patch just tries to make -mel the same as -EL and -meb and -EB.
The cc1 and linker specs already treat them the same, but the assembler
spec doesn't, and there's no MULTILIB_MATCHES entries.

Tested on mips-elf and mipsisa32-elf, and checked that

        mips-elf -mel hello.c -Tidt.ld
        mipsisa32-elf -mel hello.c -Tidt32.ld

now work.  OK to install?

	* config/mips/t-coff, config/mips/t-elf, config/mips/t-isa3264,
	config/mips/t-r3900 (MULTILIB_MATCHES): Define.
	* config/mips/mips.h (ASM_SPEC): Use %(endian_spec).
