* mipsread.c (psymtab_to_symtab_1, parse_procedure): For stabs,

	save the indices of the MIPS_EFI_SYMBOL_NAME symbol rather than
	looking them up by the names of the functions.

	* mipsread.c (mylookup_symbol): Use strcmp, not STREQ, as we have
	already checked the first characters.

        Changes from Jeffrey Law:
        * printcmd.c (makeva_list): Use MAKEVA_EXTRA_INFO to define
        machine dependent fields in the makeva_list structure.
