Rich Felker 5c3412d225 fix regression disabling use of pause instruction for x86 a_spin ...

commits e24984efd5c6ac5ea8e6cb6cd914fa8435d458bc and
16b55298dc4b6a54d287d7494e04542667ef8861 inadvertently disabled the
a_spin implementations for i386, x86_64, and x32 by defining a macro
named a_pause instead of a_spin. this should not have caused any
functional regression, but it inhibited cpu relaxation while spinning
for locks.

bug reported by George Kulakowski.
