Enable __float128 tests for x86 will lead to failures on ia32

of __float128 optimized for x86 and x86-64, I don't know if I
should spend time on porting 128bit soft-fp to x86.
Well, soft-fp implementation in gcc has all the required features
(exceptions, rounding modes, denormals) and is one of the fastest
implementations of software FP [1]. Since it is shared with glibc
soft-FP, it also passes tests from glibc.
