glibc: Do not synthesize wordsize.h for arm multilibs
This has been constant source of trouble, because it is fundamental file
which sets machine word length and everything else builts on top of that
so when it is sythesized like this, where the sythesize template itself
needs wordsize.h to determine machine word length, it creates the
catch-22 problem, which is seen when building things like bpf, or
running clang-tidy etc. where compiler internal defines may not be used
this ends up in all sorts of problems. Now that glibc provides exact
same header for arm and aarch64, its no longer needed to be multilibbed
