This patch consolidates the poll Linux syscall implementation on
sysdeps/unix/sysv/linux/poll.c. It basically removes poll from
auto-generation list and add a default implementation that either
call __NR_poll directly (if the kernel headers defines it) or
ppoll adjusting the timeout argument (as the generic implementation).
Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.
* sysdeps/unix/sysv/linux/generic/poll.c: Remove file.
* sysdeps/unix/sysv/linux/poll.c: New file.
* sysdeps/unix/sysv/linux/syscalls.list: Remove poll from
auto-generation list.

This patch changes the way cancellation entrypoints are defined to
instead call the macro SYSCALL_CANCEL. An usual cnacellation definition
is defined as:
if (SINGLE_THREAD_P)
return INLINE_SYSCALL (syscall, NARGS, args...)
int oldtype = LIBC_CANCEL_ASYNC ();
return INLINE_SYSCALL (syscall, NARGS, args...)
LIBC_CANCEL_RESET (oldtype);
And it is rewrited as just:
SYSCALL_CANCEL (syscall, args...)
The idea is to remove LIBC_CANCEL_ASYNC/LIBC_CANCEL_RESET explicit
usage.
Tested on i386, x86_64, powerpc32, powerpc64le, arm, and aarch64.

Now that files using __ASSUME_* macros have been made by
<https://sourceware.org/ml/libc-alpha/2014-06/msg00543.html> to
include <kernel-features.h> directly, any include from a file not
using __ASSUME_* macros can safely be removed (as there will no longer
be some other file relying on indirect inclusion via a header from
which the include is being removed).
This patch removes such unnecessary kernel-features.h includes.
Tested x86_64 that disassembly of installed shared libraries is
unchanged by this patch, except for line numbers in calls to
__assert_fail from libc.so and ld.so.

I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy,
along with the linux-generic ports infrastructure. Beyond the README
update, the move was just
git mv ports/sysdeps/tile sysdeps/tile
git mv ports/sysdeps/unix/sysv/linux/tile \
sysdeps/unix/sysv/linux/tile
git mv ports/sysdeps/unix/sysv/linux/generic \
sysdeps/unix/sysv/linux/generic
I updated the relevant ChangeLogs along the lines of the ARM move
in commit c6bfe5c4d75 and tested the 64-bit tilegx build to confirm that
there were no changes in "objdump -dr" output in the shared objects.
