math: fix ld80 acoshl(x) for x < 0
acosh(x) is nan for x < 1, but x < 0 cases were not handled specially and acoshl gave wrong result for some -0x1p32 < x < -2 values, e.g.: acoshl(-0x1p20) returned -inf, acoshl(-0x1.4p20) returned -0x1.db365758403aa9acp+0L, fixed by checking the sign bit and handling it specially. reported by Paul Zimmermann.
