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
