Add Makefile infrastructure, a format-specific test skeleton providing a data comparison implementation that ignores bits of data representation in memory that do not participate in holding floating-point data, and `long double' real input data for targets using the Intel/Motorola 80-bit format. Keep input data disabled and referring to BZ #12701 for entries that are are currently incorrectly accepted as valid data, such as '0e', '0e+', '0x', '0x8p', '0x0p-', etc. Reviewed-by: Joseph Myers <josmyers@redhat.com>
