[ Upstream commit 239df3e4b4 ]
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 and glibc.
However on musl we get the follwing error without sys/time.h
samples/mei/mei-amt-version.c: In function 'mei_recv_msg':
samples/mei/mei-amt-version.c:159:24: error: storage size of 'tv' isn't known
159 | struct timeval tv;

Hence the the file has been included.
