Subject: grub2: fix build

grub2 now builds fine, but some work remains to make it usable. What
should be installed exactly in the TARGET_DIR ? What is the
installation procedure and what should Buildroot do ?

+# TODO

+#  * grub2's autogen uses ruby, which isn't part of the core Debian
+#    installation. So either decide it is a requirement for Buildroot,
+#    or build it for the host.
+#
+#  * improve the installation procedure. For the moment, it just
+#    installs everything in $(TARGET_DIR).
