File arch-mips/sigsetjmp.S includes <asm-generic/portability.h>
already defined in LOCAL_CFLAGS, and build system prior JB
passes LOCAL_CFLAGS for building *.S as well, but no more >=JB.
Use LOCAL_C_INCLUDES instead (pass for *.S too)

ARM expanse some functions to others. For example,
_Unwind_GetIP will be inlined to _Unwind_GetGR, which
will be inlined to _Unwind_VRS_Get. This happens at
header-included level.
However, we use Itanium _Unwind_* header as portable one.
We do the inlining in ARM libportable to prevent
undefined reference to these functions.

The portable (ARM) jmp_buf and sigjmp_buf structures are smaller than the native
(MIPS) structures so it is not safe to simply call the standard bionic routines.
Luckily there is a lot of redundant space in the standard MIPS structures
and it is possible to save all of the needed registers in the area provided by the
ARM application.

Specifically these functions are now supported:
signalfd4(), eventfd(), timerfd_create(),
pipe(), and inotify_init1()
Modified syscall_portable() to call signalfd4_portable(),
eventfd_portable(), eventfd2_portable(), and timerfd_create().
These system calls enable the read system calls to access
kernel data structures.
The signalfd4() enables read to return a signalfd_siginfo structure
which have the signal number and errno mapped until an execve().
This is similar to the maintaining a table of signal handlers to
map the signal numbers done earlier. This mapping is extended to
the process after an execve() by passing the final set of mapped
file descriptors via a pair of environment variables.
Disabling signal and file descriptor read mapping in parent
if the child would break the mapping algorithms.
This code passes at least all of the non-POSIX LTP tests,
including an updated LTP signalfd4 test that posts SIGNALS
and uses this read() mechanism to get signal info.
inotify_init1 is similar to signalfd(), timerfd() and other
filefd functions which map read() calls. Unlike signalfd(), and
similar to timerfd(), the reads don't appear to need to be mapped.
The members of the inotify_event structure appear to be generic.
The mask bits like IN_MOVE_FROM and IN_MOVE_TO are defined in
generic files. The LTP test in testcases/kernel/syscalls/inotify
test for the inotify_event structure being inotify_event structure
being read and does seem to check it contents being correct.

Unifying around the <class>_ntop() style;
changing ntop_*() and pton_* to *_ntop() and *_pton().
Also added portable versions of strerror() and strerror_r()
while updating the errno.c file.
