commit aefb980c45134d84f1757de1a9c61d699c8a7e33
Author: Richard Levitte <levitte at openssl.org>

    crypto/uid.c: use own macro as guard rather than AT_SECURE
    
    It turns out that AT_SECURE may be defined through other means than
    our inclusion of sys/auxv.h, so to be on the safe side, we define our
    own guard and use that to determine if getauxval() should be used or
    not.
    
    Fixes #7932
