commit 5bc62e01cd22ea1f56bde94b0616c46f8af2676e
Author: Gerd Hoffmann <kraxel@redhat.com>

    build: allow turning off debuginfo
    
    This patch adds --{enable,disable}-debug-info switches to configure
    which allows to include/exclude the '-g' switch on the gcc & ld
    command lines.  Not building debug info reduces ressource usage
    (especially disk) alot and is quite useful for test builds.
