eval.c: Only inline float_op_wrapper on non-i386 #3072

glibc on i386 seems to have an optimization that makes it harder to call
some math functions indirectly from inside an inlined function, causing
compile-time errors with some versions of gcc.  This removes inlining on
that platform.

Closes #3071
