newlib: Add non LDBL_EQ_DBL math support for aarch64, i386, and x86_64

    Rename s_nearbyint.c, s_fdim.c and s_scalbln.c to remove conflicts
    Remove functions that are not needed from above files
    Modify include paths
    Add includes missing in cygwin build
    Add missing types
    Create Makefiles
    Create header files to resolve dependencies between directories
    Modify some instances of unsigned long to uint64_t for 32 bit platforms
    Add HAVE_FPMATH_H
