The latest changes are causing a build breaks. The first problem is with 
the tricky include recussion in nptl/sysdeps/pthread/sigaction.c. With 
the new directory structure it is getting the ENOSYS stub instead of the 
__libc_sigaction from sysdeps/unix/sysv/linux. This seems to be problem 
for any arch that does not have a arch specific sigaction down the 
sysdeps/unix/sysv/linux path (powerpc being an example).

Placing a include stub in sysdeps/unix/sysv/linux/powerpc/sigaction.c is 
an effective work around.

There also seems to be a problem with the declaration of 
__libc_cleanup_routine in libc-lock.h (at least with gcc-3.4) still 
looking at this one ...
