Add a layer of macro indirection for long double files which need to be built using another typename. Likewise, add the L(num) macro used in a later patch to override real constants. These macros are only defined through the ldbl-128 math_ldbl.h header, thereby implicitly restricting these macros to machines which back long double with an IEEE binary128 format. Likewise, appropriate changes are made for the few files which indirectly include such ldbl-128 files. These changes produce identical binaries for s390x, aarch64, and ppc64.
