isnanl, isfinite, snan: Improve cross-compilation guess.

* m4/exponentl.m4 (gl_LONG_DOUBLE_EXPONENT_LOCATION): When
cross-compiling, invoke gl_LONG_DOUBLE_VS_DOUBLE and
gl_DOUBLE_EXPONENT_LOCATION, and guess the result depending on the CPU.
* modules/getpayloadl (Depends-on): Add exponentd.m4, math_h.m4.
* modules/isfinite (Depends-on): Likewise.
* modules/isnanl (Depends-on): Likewise.
* modules/setpayloadl (Depends-on): Likewise.
* modules/setpayloadsigl (Depends-on): Likewise.
* modules/isnanl-nolibm (Depends-on): Add exponentd.m4.
