Since glibc 2.28 has added the statx function after commit
fd70af45528d ("Add the statx function"), stat_test.c will include
/usr/include/bits/statx.h eventually by "include <sys/stat.h>". That
causes the STATX_TYPE has already been defined before include
"status.h", then xfstests_statx will not be defined.
So make fails with the following error message:
/usr/bin/ld: /tmp/cc2Isfch.o: in function `main':
/home/luke/workspace/xfstests-dev/src/stat_test.c:690: undefined reference to `xfstests_statx'
/usr/bin/ld: /tmp/cc2Isfch.o: in function `get_reference':
/home/luke/workspace/xfstests-dev/src/stat_test.c:301: undefined reference to `xfstests_statx'
/usr/bin/ld: /tmp/cc2Isfch.o: in function `main':
/home/luke/workspace/xfstests-dev/src/stat_test.c:642: undefined reference to `xfstests_statx'
Just move out the definition of xfstests_statx between "#ifndef
STATX_TYPE" and "#endif /* STATX_TYPE */".
