Mpersify parsers of struct stat and struct stat64 On many architectures that support multiple personalities, struct stat differ between personalities. While old code could handle these differences, there are some architectures, e.g. sparc64, that also have different struct stat64. Rewrite parsers using mpers functionality to fix these issues. * fetch_struct_stat.c: New file. * fetch_struct_stat64.c: Likewise. * print_struct_stat.c: Likewise. * oldstat.c: Likewise. * stat.c: Likewise. * stat.h: Likewise. * stat64.c: Likewise. * file.c: Remove. * printstat.h: Likewise. * linux/aarch64/stat32.h: Likewise. * linux/powerpc64/stat32.h: Likewise. * linux/riscv/stat32.h: Likewise. * linux/sparc64/stat32.h: Likewise. * linux/tile/stat32.h: Likewise. * linux/x32/stat32.h: Likewise. * linux/x86_64/stat32.h: Likewise. * Makefile.am (strace_SOURCES): Add fetch_struct_stat.c, fetch_struct_stat64.c, print_struct_stat.c, oldstat.c, stat.c, stat.h, and stat64.c.
