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.
