This adds a test case for Multiboot memory map in the tests/multiboot directory, where future i386 test kernels can be dropped. Because this requires an x86 build host and an installed 32 bit libgcc, the test is not part of a regular 'make check'. The reference output for the test is verified against test runs of the same multiboot kernel booted by some GRUB 0.97. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
