commit 673e230560ac874deed6993d8b9ebaf82e73c408
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Thu Feb 1 10:31:57 2018 -0200

    stdlib: Fixing test-*atexit*-race tests on ia64
    
    These tests require a new thread stack size set to a value (0x20000)
    lower than the architecture minimum (0x30000).  Set the stack size
    to PTHREAD_STACK_MIN in this case.
    
    Checked on ia64-linux-gnu.
    
    	* stdlib/test-atexit-race-common.c (do_test): Check stack size
    	against PTHREAD_STACK_MIN.
