As reported by Matthew Weber, Grub doesn't build on 64 bits build
machines, because the host compiler produces 64 bits binaries by
default, while Grub should be built 32 bits. Therefore, this commit
passes -m32 to the Grub CFLAGS, so that 32 bits binaries are always
produced.

These instructions should probaby go in the Buildroot manual, but at
this point, it's not clear in which section they should go. So in
order to not loose those notes, add them to the Grub help text.

Grub can be configured to enable or disable the filesystems supported
in the stage 2. In addition, there are filesystem specific stage
1.5. In order to save space and build time, we provide a new option
that allows to give a space-separated list of filesystems that Grub
should support.
We default to support FAT and ext2, since most of the other
filesystems are fairly unlikely to be used.
We use this option to:
1) Pass --enable-<fs> or --disable-<fs>, which enables/disables the
support of <fs> in Grub stage 2.
2) Install only the stage 1.5 that correspond to the selected
filesystems.

Two improvements to the menu.lst file:
* Do not enforce any video mode, let the kernel use whatever it wants
as the default, or let the user customize it when needed.
* Use /dev/sda1 instead of /dev/hda1. Nowadays, most hard disk
controllers are handled using libata, and therefore the disks are
visible as /dev/sd<X>.

This commit brings a number of improvements to the grub packaging:
* It builds grub with the host compiler, which is needed so that we
can build a 32 bits grub even if the target architecture is
x86-64. To make sure we have a host compiler capable of generating
32 bits code, grub now selects the BR2_HOSTARCH_NEEDS_IA32_COMPILER
option. Building with the host compiler is done by cheating and
passing $(HOST_CONFIGURE_OPTS) in GRUB_CONF_ENV.
* Some additional CFLAGS are added to make sure grub builds properly
with modern compilers (-O0, --build-id=none, -fno-stack-protector).
* Removal of the GRUB_INSTALL_STAGING_CMDS which were not used, since
GRUB_INSTALL_STAGING was not set to YES.
* Installation of the "grub" binary in $(HOST_DIR) instead of
$(TARGET_DIR) since it's actually used only on the host to install
grub into an image or device.
* Removal of the grub uninstall commands, since they are generally
considered useless.

Thanks to the pkgparentdir and pkgname functions, we can rewrite the
AUTOTARGETS macro in a way that avoids the need for each package to
repeat its name and the directory in which it is present.

Closes#4093
AUTOTARGETS doesn't handle compressed patches, so the '400' patch did
not get applied.
Fix it by extracting the patch. With this, the '500' patch is no longer
needed.

As the kernel and bootloaders do not use the normal BR2_PACKAGE_*
Kconfig options, their target name was not automatically added to the
global TARGETS variable. Each bootloader .mk and the linux.mk had to
add their own target manually to TARGETS, and the package
infrastructure was making tests on non-existing Kconfig variables.
This commit improves the package infrastructure so that it looks at
BR2_PACKAGE_<pkg> for packages, BR2_TARGET_<pkg> for bootloaders and
at the special BR2_LINUX_KERNEL for the linux package.
This allows to simplify a little bit the bootloaders and linux .mk
files.
