[PATCH] Define wordsize.h macros everywhere

[Joseph Myers]

I see errors in tilepro-linux-gnu builds with this patch:

../sysdeps/generic/stdint.h:252:7: error: "__WORDSIZE32_PTRDIFF_LONG" is not defined [-Werror=undef]
 #  if __WORDSIZE32_PTRDIFF_LONG
       ^~~~~~~~~~~~~~~~~~~~~~~~~
../sysdeps/generic/stdint.h:269:7: error: "__WORDSIZE32_SIZE_ULONG" is not defined [-Werror=undef]
 #  if __WORDSIZE32_SIZE_ULONG
       ^~~~~~~~~~~~~~~~~~~~~~~
