Merge libm-compat-calls-auto and libm-compat-calls

Both libm-compat-calls and libm-compat-calls-auto list the functions
that must be built for the types float, double, and long double, but
not for other floating-point types that get added to libm.  Besides
that, the use of libm-compat-calls-ldouble-yes to select if
w_lgamma_compatl and k_standardl should be built for long-double (in
libm-compat-calls) has the same effect of the use of type-foreach
(in libm-compat-calls-auto).

This patch merges the contents of libm-compat-calls into
libm-compat-calls-auto, then renames the latter to libm-compat-calls.

Tested for powerpc64le, s390, and x86_64.

	* math/Makefile (libm-compat-calls-ldouble-yes): Merge into
	libm-compat-calls-auto.
	(libm-compat-calls): Likewise.
	(libm-compat-calls-auto): Rename to libm-compat-calls and add
	w_lgamma_compatF and k_standardF (merged from the items above).
	(libm-routines): Use libm-compat-calls, instead of
	libm-compat-calls-auto, with type-foreach.
