* config/tc-mips.h: Define TARGET_FORMAT if OBJ_ELF.
* config/tc-mips.c (GPOPT): Define if OBJ_ECOFF or OBJ_ELF. (various): Change all references to GP references to apply if GPOPT, not if OBJ_ECOFF. (s_change_sec): Rearrange somewhat. If OBJ_ELF, use .rodata instead of .rdata. If OBJ_ELF, set section flags for .rodata and .sdata sections. (s_frame, s_loc, s_mask): Comment out entire functions, rather than just body. They're not used anyhow. * configure.in: Set cpu_type to mips for mips*. Accept mips-*-elfl* and mips-*-elf*.
