Read the glibc FAQ, it mentions stat:
2.7. Looking through the shared libc file I haven't found the
functions `stat', `lstat', `fstat', and `mknod' and while
linking on my Linux system I get error messages. How is
this supposed to work?
{RM} Believe it or not, stat and lstat (and fstat, and mknod) are supposed
to be undefined references in libc.so.6! Your problem is probably a missing
or incorrect /usr/lib/libc.so file; note that this is a small text file now,
not a symlink to libc.so.6. It should look something like this:
GROUP ( libc.so.6 libc_nonshared.a )
