The header bits/wordsize.h is glibc specific and on building on musl
with allyesconfig results in

samples/mei/mei-amt-version.c:77:10: fatal error: bits/wordsize.h: No such file or directory
   77 | #include <bits/wordsize.h>
      |          ^~~~~~~~~~~~~~~~~

mei-amt-version.c build file without bits/wordsize.h on musl. I'm not
sure we can remove the header completely or how it's used under glibc.

Can you look into that instead of just adding a #ifdef that might not
actually be needed?

Did some testing and it seems like we can remove the bits/wordsize.h. It
does not affect build on either glibc or musl.
I'll send a patch.
