    testsuite: Fix up gcc.target/i386/pr109137.c testcase [PR109137]
    
    The testcase has a couple of small problems:
    1) had -m32 in dg-options, that should never be done, instead the test
       should be guarded on ia32
    2) adds -fPIC unconditionally (that should be guarded on fpic effective
       target)
    3) using #include <string.h> for a RA test seems unnecessary, __builtin_memset
       handles it without the header

            * gcc.target/i386/pr109137.c: Remove -m32 from dg-options, instead
            require ia32 effective target.  Only add -fPIC for fpic effective
            target.  Remove #include <string.h>, use __builtin_memset instead of
            memset.
