wordsize.h for x86-64

wordsize.h for x86-64

[Andreas Jaeger]

I'd like to follow the example of Sparc in using __WORDSIZE in the
glibc headers of x86-64 to allow compilation with both 32-bit and
64-bit compilers of the same headers.

Since this first appended patch affects also i386, I'd like to get
permission to commit this file to both branches.

	* sysdeps/i386/bits/wordsize.h: New file to allow sharing with
	x86-64.
	* sysdeps/x86_64/bits/wordsize.h: Likewise.

I don't see why the x86 file change is needed.  Any x86_64 system will
have the x86_64 libraries installed as the main libraries.  There will
be the binaries for the x86 library but it doesn't come with headers.

Ok, that makes sense.  I'll add the file later with the other changes
after testing it properly,

Thanks,
Andreas
