* math/Makefile (libm-support, libm-calls): New variables.
(libm-routines): Construct this from those.
(calls): New variable.
(routines): Construct this from it.
* math/Makefile (long-m-routines): Define recursive variable as
$(long-m-$(long-double-fcts)).
(long-m-yes): Put list of routines here.
(long-c-routines, long-c-yes): Likewise.
* math/Makefile [$(long-double-fcts)!=yes] (CPPFLAGS): Append
  -DNO_LONG_DOUBLE.
