matter which completes first, both write the same to __gmpn_cpuvec.

dnl Usage: FAT_INIT(name, offset)
dnl
dnl Emit a fat binary initializer function of the given name. These
dnl functions are the initial values for the pointers in __gmpn_cpuvec.
dnl
dnl The code simply calls __gmpn_cpuvec_init, and then jumps back through
dnl the __gmpn_cpuvec pointer, at the given "offset" (in bytes).
dnl __gmpn_cpuvec_init will have stored the address of the selected
dnl implementation there.
dnl
dnl Only one of these routines will be executed, and only once, since after
dnl that all the __gmpn_cpuvec pointers go to real routines. So there's no
dnl need for anything special here, just something small and simple. To
dnl keep code size down, "fat_init" is a shared bit of code, arrived at
dnl with the offset in %al. %al is used since the movb instruction is 2
dnl bytes where %eax would be 4.
