Rich Felker 5c3412d225 fix regression disabling use of pause instruction for x86 a_spin
commits e24984efd5 and
16b55298dc 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.
