libm/x86: use call instead of jump for wrappers
GCC can emit prologue/epilogue code for the functions in various
different cases:
- frame pointers
- PIC build (to load ebx for indirect calls/jumps)
- forced stack smashing protection
If we used jump in such cases, we'd corrupt the call stack and
crash.
