commit 1f8e36720fff9bdc9f08fe24a38cc91b1b78ddb0
Author: Mattias Ellert <mattias.ellert at physics.uu.se>

    Openssl fails to compile on Debian with kfreebsd kernels
    (kfreebsd-amd64, kfreebsd-i386). The error reported by the compiler
    is:
    
    ../crypto/uid.c: In function 'OPENSSL_issetugid':
    ../crypto/uid.c:50:22: error: 'AT_SECURE' undeclared (first use in this function)
       50 |     return getauxval(AT_SECURE) != 0;
          |                      ^~~~~~~~~
    
    This commit changes the code to use the freebsd code in this case.
    This fixes the compilation.
