No value for `fnlibquadmath'

[Lars Ljung]

The info pages for gcc-doc adds the following entry to the info dir file:

* {No value for 'fnlibquadmath'}: ({No value for `fnlibquadmath'}).
                                GCC Quad-Precision Math Library

The entry is invalid and it is not possible to reach the info page for fnlibquadmath.
