Make Irix 5 configuration work again: 

* config/obj-multi.h (obj_frob_symbol, obj_frob_file, S_GET_SIZE, S_SET_SIZE,
S_GET_ALIGN, S_SET_ALIGN, obj_copy_symbol_attributes, OBJ_PROCESS_STAB): New
macros.
* config/tc-mips.c: Protect against redefining them also when including
obj-elf.h.  Test only OBJ_ELF for including elf/mips.h.

OBJ_PROCESS_STAB): New macros.

* read.c (s_lcomm): Do ELF/ECOFF test at run time, not compile
time.
