[Bug target/30936] __builtin_nanf("") != __builtin_nanf("") is false for sh4-linux-gnu

Actually it turns out this is not a bug but rather you did not read the full
documentation:
http://gcc.gnu.org/onlinedocs/gcc-4.1.0/gcc/SH-Options.html

-mieee
Increase IEEE-compliance of floating-point code. At the moment, this is
equivalent to -fno-finite-math-only. When generating 16 bit SH opcodes, getting
IEEE-conforming results for comparisons of NANs / infinities incurs extra
overhead in every floating point comparison, therefore the default is set to
-ffinite-math-only.
