[PATCH v3 7/7] MIPS: Fix Irix gas testcases

[YunQiang Su <yunqiang.su@cipunited.com>]

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. Add irix-no-pdr.d.

3. Add and use call-nonpic-1-irix.d for Irix targets.
   Gas doesn't set O32 flags for Irix objects in e_flags.  See
   `use_e_mips_abi_o32` in gas/configure.ac.

4. Add mips16-e-irix.d: g1 is marked as O on Irix.
   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.
