* 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.
