commit 5eec04a43e6c562e956353449be931dd43dfe1cc
Author: Werner Koch <wk at gnupg.org>
Date:   Tue Sep 2 09:25:20 2014 +0200

    asm: Allow building x86 and amd64 using old compilers.
    
    * src/hwf-x86.c (get_xgetbv): Build only if AVX support is enabled.
    --
    
    Old as(1) versions do not support the xgetvb instruction.  Thus build
    this function only if asm support has been requested.
    
    GnuPG-bug-id: 1708
