test/math: add fallback to libm-test-ulps-generic logic

Under test/math/, there is libm-test-ulps-generic used as fallback
in case that libm-test-ulps-$(TARGET_ARCH) does not exist.

This is required for arches that don't have ULPS yet.

ARC/NPTL: clone to set TP if CLONE_SETTLS

Typically kernel would set the TP register of newly created thread in
clone syscall with CLONE_SETTLS.

However this implies that:
* kernel knows of the exact TP register (which is already different for
  ARCompact and ARCv2) and is a detail which becomes part of the ABI
* kernel also needs to handle the unlikely but possible case of !TLS
  userspace (e.g. Android libc) case where TP reg is not reserved and
  thus need not be mucked with (using ELF personality based detection)

It is better to confine this detail to userspace runtime and set TP reg
right after clone syscall returns.

test_nptl: replace __sigpause with sigpause

On attempt to build uClibc tests following error message appears:
=========
TEST_LINK nptl/ tst-cancel4
tst-cancel4.c: In function 'tf_sigpause':
tst-cancel4.c:765:3: warning: implicit declaration of function
'__sigpause' [-Wimplicit-function-declaration]

^
tst-cancel4.o: In function `tf_sigpause':
tst-cancel4.c:(.text+0x1054): undefined reference to `__sigpause'
collect2: error: ld returned 1 exit status
=========

This commit http://git.uclibc.org/uClibc/commit/?id=cef1f9517c319d86b4b426ecc14a10d0fa5494c7
makes __sigpause static limiting its scope to "libc/signal/sigpause.c".

Switching to common implementation "sigpause()" fixes this issue.

unbreak networking code for sparc

This commit 1e2e4ac6193ffe0900bd392fa3c596883771eb34 breaks networking
on sparc systems. In Linux the socket functions are declared, but not
implemented and must be routed through socketcall().

Tested via Qemu 2.0.0.

libc: posix_fadvise: Fix build breakage for !LFS

commit 00571b43df2e "libc: posix_fadvise: restore implementation for xtensa"
enabled posix_fadvise() for all arches (it was just not generated
before).

However this also unearthed an issue introduced by ee84b8b400
"linux: posix_fadvise: use new SYSCALL_ALIGN_64BIT" which is to
referencing LFS'ish code (off64_t) w/o proper checks which causes build
to break for !LFS.

Fix this by calling posix_fadvise64() only for LFS case and open-code
it's equivalent for !LFS.

lseek: Correct order of offset arguments

There was a runtime error in systems without large file support. Call
fseek(fd, 4096, SEEK_SET) has been failing with EINVAL, though it was
succeeding for offset = 4092. This has been happening because llseek system
call accepts 64-bit value as an offset argument and lseek function has been
ordering 32-bits words that form this offset value, according to the
endianness. However this ordering to match endianness is not required,
because llseek doesn't accept one 64-bit offset argument, it accepts two
32-bit offset argument, then stitches them into one following its
endianness. As a result on little endian system, order of words has been
swapped two time: in libc and in kernel. Thus call to fseek with offset 4096
(0x1000) was doing a system call to llseek with offset 0x1000_0000_0000. I'm
not entirely sure why then offset = 4092 hasn't been failing then.

This patch removes malicious swap of words when calling llseek.

test/math: fix for disabled long double math

Commit "test: cater for config" http://git.uclibc.org/uClibc/commit/test/math/Makefile.in?id=7598eeaa1defa2884adaa890bb115c493d69cc35 inverted check from
	ifeq ($(UCLIBC_HAS_LONG_DOUBLE_MATH),y)
to
	ifeq ($(UCLIBC_HAS_LONG_DOUBLE_MATH),)
with first branch indeed inverted - instead of adding tests they were excluded.
But "else" branch was not moved up (remember check was inverted).

This causes compile breakage when building basic-test.c:
--->---
TEST_LINK math/ basic-test
basic-test.c: In function 'ldouble_test':
basic-test.c:111:1: warning: implicit declaration of function 'nanl' [-Wimplicit-function-declaration]

collect2: error: ld returned 1 exit status

Fix is simple - merge "old else" branch with the first current one.

libc: add issetugid()

issetugid() returns 1 if the process environment or memory address space
is considered tainted, and returns 0 otherwise.  This happens, for example,
when a process's privileges are elevated by the setuid or setgid flags on
an executable belonging to root.  This function first appeard in OpenBSD 2.0
and is needed for the LibreSSL.

This patch follows the same logic as the equivalent musl commit.  For more
information see the commit message at
