Consolidate non cancellable writev call
This patch consolidates all the non cancellable writev calls to use the __writev_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. * gmon/gmon.c (write_hist): Replace writev_not_cancel_no_status with __writev_nocancel_nostatus. (write_call_graph): Likewise. (write_bb_counts): Likewise. * resolv/herror.c (herror): Likewise. * sysdeps/generic/not-cancel.h (writev_not_cancel_no_status): Remove macro. (__writev_nocancel_nostatus): New macro. * sysdeps/unix/sysv/linux/not-cancel.h (writev_not_cancel_no_status): Remove macro. (__writev_nocancel_nostatus): New function.
