commit 67ac0f74a4a5021f77566fdbe4cda5880eba8ba4
Author: Adhemerval Zanella <adhemerval.zanella@linaro.com>
Date:   Mon Sep 21 15:54:04 2015 -0700

    nptl: Add NPTL cases for cancellation failures cases
    
    This patch pthread cancellation tests to check for failures cases
    wherer the syscall cancel wrapper should both set the error and
    the errno values.
    
    Tested on i686, x86_64, x32, powerpc64le, and aarch64.
    
    	* nptl/Makefile (tests): Add tst-cancel26.c and tst-cancel27.c.
    	* nptl/tst-cancel26.c: New file.
    	* nptl/tst-cancel27.c: Likewise.
