[Bug libc/2418] New: getcwd() print an assertion for a path greater than MAX_PATH

Here is the code which causes problem, in sysdeps/unix/sysv/linux/getcwd.c :
/* It should never happen that the `getcwd' syscall failed because
the buffer is too small if we allocated the buffer ourselves
large enough. */
assert (errno != ERANGE || buf != NULL || size != 0);
The buffer allocated by the code before is of size MAX_PATH. So if the actual
size of the path on the filesystem is greater than MAX_PATH, an assertion is
printed.
That proves that it could happen! I suggest simply removing the assertion, as
the function then just exits with the error code.
Note that the problem only occurs on ia64, on other platforms the error number
returned is ENAMETOOLONG (see bug 2417)
