[PATCH 2/2] MIPS: fix Irix gas testcases

[YunQiang Su]

1. add -mpdr to some cases.
   gas doesn't generate .pdr section for Irix objects by default. See
   `int mips_flag_pdr` in tc-mips.c.
2. disable call-nonpic-1 for Irix.
   gas doesn't set O32 flags for Irix objects in e_flags. See
   `use_e_mips_abi_o32` in gas/configure.ac.
3. mips16-e.d: g1 may be marked as O.
   The Irix 5 and 6 assemblers set the type of any common symbol and
   any undefined non-function symbol to STT_OBJECT.
   See `mips_frob_symbol` in tc-mips.c.
