tests: check verbose decoding of 32-bit and 64-bit struct stat
* tests/stat.c: New file.
* tests/stat32.c: Likewise.
* tests/stat32-v.test: New file.
* tests/stat64-v.test: Likewise.
* tests/Makefile.am (check_PROGRAMS): Add stat and stat32.
(stat_CFLAGS): Define.
(TESTS): Add stat32-v.test and stat64-v.test.
* tests/.gitignore: Add stat and stat32.
