The event code is PTRACE_EVENT_SECCOMP, not PTRAVE_EVENT_SECCOMP.
This patch fixes the V->C typo. There are no ABI issues since the
number remains the same for the code. Code using the old wrong
name will need to be updated.

This patch helps some math functions performance by adding the libc_fexxx
variant of inline functions to handle both FPU round and exception set/restore
and by using them on the libc_fexxx_ctx functions. It is based on already coded
fexxx family functions for PPC with fpu.
Here is the summary of performance improvements due this patch (measured on a
POWER7 machine):

As detailed in PR11157, the use of '__block' is known to interfere
with keywords in some environments, such as the Clang -fblocks extension.
Recently a similar issue was raised concerning the use of '__unused'
and a '__glibc' prefix was proposed to create a glibc implementation
namespace for these sorts of issues [1]. This patches takes that
approach.

On hppa and ia64, the macro DL_AUTO_FUNCTION_ADDRESS() uses the
variable fptr[2] in it's own scope.
The content of fptr[] is thus undefined right after the macro exits.
Newer gcc's (>= 4.7) reuse the stack space of this variable triggering
a segmentation fault in dl-init.c:69.
To fix this we rewrite the macros to make the call directly to init
and fini without needing to pass back a constructed function pointer.

The hard alignment of 8 was appropriate for most platforms for
which 8-byte values are 8-byte aligned, but this is not true
for the nios2 platform, so only align to the alignment of the
8-byte type on the platform.
Remove the explicit alignment of struct statfs as it's redundant.

This reverts commit 78271fa91a1e6902222e892068750059ec21f396.
Actually, a different fix is needed.

Not all architectures define this value, and if they don't,
just let the test run the same as test-fpucw, with __fpu_control
set to _FPU_DEFAULT explicitly.

We first expanded origin and then split string by colons. This
misbehaves when $ORIGIN contain colon so we first split string, then
expand $ORIGIN.
