It is also happening on powerpc-linux-gnu:

------- Comment #2 from janis at gcc dot gnu dot org  2008-07-08 21:51 -------
The tests fail on powerpc*-unknown-linux-gnu with 128-bit long doubles because
__builtin_fpclassify claims that __LDBL_MAX__ is infinite, not normal.  Here's
a small testcase minimized from type-generic-1.c:

#define FP_NAN 1
#define FP_INFINITE 2
#define FP_NORMAL 3
#define FP_SUBNORMAL 4
#define FP_ZERO 5
#define fpclassify(X) __builtin_fpclassify(FP_NAN, FP_INFINITE, FP_NORMAL,
FP_SUBNORMAL, FP_ZERO, (X))

int
main ()
{
  volatile long double ld;

  ld = __LDBL_MAX__;
  if (fpclassify (ld) != FP_NORMAL)
    __builtin_abort ();

  return 0;
}
