nptl: sysdep headers re-factoring

This patch will re-factor and simplify sysdep headers
handling for nptl branch.
The reason is to use some useful macros in asm code (i.e. ENTRY()) that are available
only into nptl branch because are defined in sysdep.h header under the nptl folder
even if they are not related to NPTL at all (this was likely due to a bad choice done
at the early stage of NPTL porting).
This is a required steps for integrating into master branch some asm code available in
nptl branch for sh4.

The main changes are described below:

nptl/sysdeps/generic/sysdep.h (moved) ---> libc/sysdeps/linux/common/sysdep.h
nptl/sysdeps/arm/sysdep.h     (moved) ---> libc/sysdeps/linux/arm/sysdep.h

nptl/sysdeps/sh/sysdep.h ---------------------|
nptl/sysdeps/unix/sh/sysdep.h ----------------|
nptl/sysdeps/unix/sysv/linux/sh/sysdep.h -----|
nptl/sysdeps/unix/sysv/linux/sh/sh4/sysdep.h -|
                                              |(merged) ---> libc/sysdeps/linux/sh

nptl/sysdeps/unix/sysdep.h (deleted)

Similarly the mips and arm sysdep.h should be merged and updated as for sh arch.
