Older kernels use __NR__llseek for a 64-bit lseek syscall. Newer
kernels use __NR_llseek. This patch fixes the implementation of
lseek64 to use the __NR_llseek syscall if it exists.

The test for generating a stub for getpgrp was wrong and would
result in duplicate symbols when building without __NR_getpgrp,
but with __NR_getpgid and __NR_getpid.
A closer look at the getpgrp implementation using getpgid showed
that getpid was being called to pass the current pid to getpgid.
This is unnecessary because passing 0 to getpgid returns the
pgid of the current process.
This patch cleans up the getpgrp implementation and the stub test.

__check_pf() function is called from getaddrinfo() and it calls
getifaddrs(), which is too much overhead especially if RSBAC-Net
is enabled. So with this patch __check_pf() is being called only
when AI_ADDRCONFIG hint flag is specified - just when we really
need that check.

The current code will sometimes cast the offset to an unsigned long.
On 32bit systems, that doesn't make much sense since we always know
that the off64_t type is 64bits. So drop the ifdef logic, cast it
to an unsigned 64bit value, and then do the shift.
If the system is 32bits, and the address is still too large, then
there's really nothing we could do about it anyways, so the extra
ifdef logic wasn't helping.

Some test results:
The longer patch posted at Sun 14:46:24 +0100 made my target system
unbootable. I did not attempt to troubleshoot it, as we are focusing
our efforts on the shorter patch now.
The shorter patch posted at Mon 01:50:27 +0100 is a good start, but it
didn't completely fix the problem for me. I am posting an updated
version with a few changes at the end of this message; the patched
uClibc 0.9.32.1 tree passes both of my test cases.
My changes:
1) Need to break out of the loop on "hard" errors. Otherwise the
library call never returns:
open("/dev/null", O_RDONLY) = 4
dup2(4, 1) = 1
write(1, "hello world\n", 12) = -1 EBADF (Bad file descriptor)
write(1, "hello world\n", 12) = -1 EBADF (Bad file descriptor)
write(1, "hello world\n", 12) = -1 EBADF (Bad file descriptor)
write(1, "hello world\n", 12) = -1 EBADF (Bad file descriptor)
...
2) Move all of the error handling logic back into the "else" clause. In
particular, I believe we do not want to be checking errno unless
__WRITE() had indicated a failure, since the value may be undefined:
if (errno == EINTR
|| errno == EAGAIN
/* do we have other "soft" errors? */
) {
3) Whitespace/indentation consistency.

From: Denys Vlasenko <vda.linux@googlemail.com>
Currently, uclibc retains buffered data on stdio write errors,
and subsequent fclose and fflush will try to write it out again
(in most cases, in vain).
Which results in something like this:

When built without NPTL support (or for a sparc target), the system()
function doesn't conform to its specification. Namely, it uses signal()
to install/save/restore signal handlers, which may break applications
using custom handlers installed with sigaction(). In addition, it resets
the SIGCHLD handler to SIG_DFL instead of blocking the signal, which may
result in "lost" signals if a custom handler was installed.
Fix system() by replacing uses of signal() with appropriate calls to
sigaction() and sigprocmask().
