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.

Config.in: Introduce symbol for arches with deprecated syscalls

Linuxthreads(old and new) need deprecated syscalls to build. Existing
architectures support these system calls but new architectures don't.
This symbol has no functional change apart from hidding the Linuxthreads
symbols from arches that don't support them.

unistd: Handle !UCLIBC_HAS_GET{, SUB}OPT cases

libc/libc_so.a(getsubopt-susv3.os): In function getsubopt':

libc/libc_so.a(getsubopt.os):getsubopt.c:(.text+0x0):

The solution is to filter out the correct files when
UCLIBC_HAS_GETOPT and UCLIBC_HAS_GETSUBOPT are not defined.

inet: Move INET_RPC_{DIR, OUT} before CSRC_ALL

libc/libc_so.a(rpc_thread.oS): In function __rpc_thread_svc_max_pollfd':

libc/libc_so.a(rpc_thread.oS): In function __rpc_thread_svc_pollfd':

The CSRC_ALL variable uses the INET_RPC_DIR variable which is
initialized later on. We fix this problem by moving the
INET_RCP_{DIR,OUT} definitions before we use them in CSRC_ALL

buildsys: gen_bits_syscall_h: do not leave undefined SYS_xxx around

If we end up doing '#undef __NR_xxx', we don't want to leave the
corresponding SYS_xxx symbol defined.  So undef it too.

For example, with the ARM EABI layer, we have a bunch of legacy
syscalls that we define early on and then later undefine (such
as __NR_utime).  But we left SYS_utime defined so code that tests
for that define before using it would be broken (since it'd be
defined to a non-existent symbol).
