This patch consolidates all the non cancellable waitpid calls to use
the __waitpid_nocancel identifier. For non cancellable targets it will
be just a macro to call the default respective symbol while on Linux
will be a internal one.
Checked on x86_64-linux-gnu, x86_64-linux-gnu-x32, and i686-linux-gnu.
* libio/ioopen.c (_IO_waitpid): Replace waitpid_not_cancel with
__waitpid_nocancel.
* sysdeps/generic/not-cancel.h (waitpid_not_cancel): Remove macro.
(__waitpid_nocancel): New macro.
* sysdeps/unix/sysv/linux/not-cancel.h (waitpid_not_cancel): Remove
macro.
(__waitpid_nocancel): Replace macro with a function.
* sysdeps/unix/sysv/linux/waitpid.c (__waitpid_nocancel): New
function.
