grub2/20-grub.install
Javier Martinez Canillas ed50db379d Make 20-grub.install to generate debug BLS when MAKEDEBUG is set
If MAKEDEBUG=yes in /etc/sysconfig/kernel, then a debug menu entry should
be created. So for BLS, a debug configuration file has to be created that
contains debug kernel command line parameters.
