In the test-case of statfs from ltp-testsuite, it pass -1 to 2th
argument. eg: fstatfs(fd , -1)
When uclibc-ng parse the buf32 to buf will cause illegal address
access, the kernel will signal the process with SIGSEGV.
If we pass the -1 directly to the syscall of statfs/fstatfs, kernel
use copy_to_user() to prevent the signal of SIGSEGV and just return
EINVAL.
This is the ltp-testsuite expect.

Using __libc_fstatfs for fstatfs64 adds a small delay as it needs to
use a 32-bit data structure to get the file info and them pass them to
the 64-bit data structure which was given as a fstatfs64 argument. Using
the system call directly should make the entire process much faster.
Also fix the arguments for fstatfs64. It takes three arguments
(see fs/fstatfs.c in Linux kernel sources) so despite what the manpage
says, the size of the buffer needs to be passed as the second argument

This matches a similar change made to glibc.
No functional changes here.

Appears to build fine (several .configs tried)

in string.h and strings.h. This caught unguarded string ops in
libc/inet/ethers.c __ether_line_w() function.
I will wait for fallout reports for a week or so,
then continue converting more libc_hidden_proto's.

been working on a new config system on and off for about 6 months
now, but I've never been fully satisfied. Well, I'm finally am
happy with the new config system, so here it is. This completely
removes the old uClibc configuration system, and replaces it with
an entirely new system based on LinuxKernelConf, from
http://www.xs4all.nl/~zippel/lc/
As it turns out, Linus has just merged LinuxKernelConf into Linux
2.5.45, so it looks like I made the right choice.
I have thus far updated only x86. I'll be updating the other
architectures shortly.
