    newlib: strtold: use __builtin_nanl to avoid libm dependency
    Commit 6c212a8b7873703c4f98c6b68579b234918be83a
    ("Fix strtod ("nan") and strtold ("nan") returns wrong negative NaN")
    introduced an unconditional dependency to nanl and, in turn, to libm.
    Rather than including nanl in libc as well, just call __builtin_nanl
    from here.  Requires GCC 3.3 or later.
