The memory management system supports a debug mode that can be enabled at build time by passing "--enable-mm-debug" to the configure script. Passing the option will cause us define MM_DEBUG as expected, but in fact the reverse option "--disable-mm-debug" will do the exact same thing and also set up the define. This currently causes the build of "lib/gnulib/base64.c" to fail as it tries to use `grub_debug_malloc()` and `grub_debug_free()` even though both symbols aren't defined. Seemingly, `AC_ARG_ENABLE()` will always execute the third argument if either the positive or negative option was passed. Let's thus fix the issue by moving the call to`AC_DEFINE()` into an explicit `if test $xenable_mm_debug` block, similar to how other defines work.

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
