libc/statfs64: Skip conversion code for new architectures
Fixes the following tests in LTP statfs02_64 ( test case #5 ) The purpose of this test is to pass an invalid pointer to the statfs64 syscall and check if the kernel returns EFAULT or not. However, uClibc creates a new statfs struct which is then passed to the kernel. As a result of which, the kernel returns 0 because the newly created statfs structure is valid. But, when copying the contens of the new pointer to the old userspace one, the uClibc segfauls because the old pointer is invalid. Old architectures are doomed to suffer by this problem but new architectures can use the statfs64 syscall directly so that the userspace pointer is passed directly to the kernel and get the correct errno at the end.
