    testsuite: i386: Require dfp in gcc.target/i386/pr101346.c
    
    gcc.target/i386/pr101346.c currently FAILs on Solaris/x86:
    
    FAIL: gcc.target/i386/pr101346.c (test for excess errors)
    
    Excess errors:
    /vol/gcc/src/hg/master/local/gcc/testsuite/gcc.target/i386/pr101346.c:6:1:
    error: decimal floating-point not supported for this target
    /vol/gcc/src/hg/master/local/gcc/testsuite/gcc.target/i386/pr101346.c:7:6:
    error: decimal floating-point not supported for this target
    /vol/gcc/src/hg/master/local/gcc/testsuite/gcc.target/i386/pr101346.c:9:12:
    warning: implicit declaration of function '__builtin_fabsd128'; did you
    mean '__builtin_fabsf128'? [-Wimplicit-function-declaration]
    
    Fixed by requiring dfp support.  Tested on i386-pc-solaris2.11 and
    x86_64-pc-linux-gnu.
