    testsuite: Require bitint in gcc.dg/torture/bitint-101.c
    
    The new gcc.dg/torture/bitint-101.c test FAILs on Solaris/SPARC:
    
    FAIL: gcc.dg/torture/bitint-101.c   -O0  (test for excess errors)
    UNRESOLVED: gcc.dg/torture/bitint-101.c   -O0  compilation failed to produce executable
    
    Excess errors:
    gcc.dg/torture/bitint-101.c:4:1: sorry, unimplemented: '_BitInt(2)' is not supported on this target
    gcc.dg/torture/bitint-101.c:11:3: sorry, unimplemented: '_BitInt(2)' is not supported on this target
    
    Fixed by requiring bitint support.
    
    Tested on sparc-sun-solaris2.11 and i386-pc-solaris2.11.
