math: Fix `unknown type name '__float128'` for clang 3.4 to 3.8.1 (bug 32694)
When compiling a program that includes <bits/floatn.h> using a clang version
between 3.4 (included) and 3.8.1 (included), clang will fail with `unknown type
name '__float128'; did you mean '__cfloat128'?`. This changes fixes the clang
prerequirements macro call in floatn.h to check for clang 3.9 instead of 3.4,
since support for __float128 was actually enabled in 3.9 by:
