Looks like this might need some config-fu:

pread.o: In function `do_pread':
/src/git/xfsprogs/io/pread.c:198: undefined reference to `preadv'
/src/git/xfsprogs/io/pread.c:198: undefined reference to `preadv'
pwrite.o: In function `do_pwrite':
/src/git/xfsprogs/io/pwrite.c:85: undefined reference to `pwritev'
/src/git/xfsprogs/io/pwrite.c:85: undefined reference to `pwritev'
sync_file_range.o: In function `sync_range_f':
/src/git/xfsprogs/io/sync_file_range.c:87: undefined reference to `sync_file_range'
