Improve TARGETS handling for bootloaders and kernel

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.

Without an mdev.conf file installed, mdev generates some /dev entries in

 1. /dev/null has permissions 660, but it should be accessible to normal
    users;
 2. alsa devices get created in /dev, not /dev/snd as is more common,
    and as the default value of BR2_PACKAGE_ALSA_LIB_DEVDIR suggests;
 3. event<N> files are created in /dev, not /dev/input.

This mdev.conf is a selection from the examples provided in the busybox

grub2: remove package

Grub 2 has been marked BROKEN in June 2010, and nobody cared to fix it
since then.

At that time, it was marked broken because the build process needed a
Ruby interpreter available on the host, and it's really a pain that
building a bootloader needs such a thing.

I've tried to upgrade the package to Grub2 1.99-rcX, and now it does
not need a Ruby interpreter anymore, but instead requires a tool
called "autogen", which itself needs the Guile Scheme interpreter.

Since we haven't heard any complaints about Grub2 being marked broken,
and since it's such a pain to package, let's get rid of it. Of course,
anybody interested in Grub2 is invited to contribute a working
package.

libgtk2: fix host build after 7a41cbf938d (fix patching procedure for host packages)

Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

package: fix patching procedure for host packages

The patching procedure was using $($(NOHOSTPKG)_NAME) to find the name
of the package without the host- prefix for host packages, which is
needed to find the package directory and the prefix of the patches.

However, this $($(NOHOSTPKG)_NAME) variable is empty when there is
only an host variant for the package and no target variant for it.

Therefore, instead of using this $($(NOHOSTPKG)_NAME) variable, we now
use a new $(RAWNAME) variable, which is always the name of the package
without the host- prefix, even for host packages.

When using GENTARGETS (or macroes depending on it), there is no way of

simply define $(PACKAGE_NAME)_EXTRACT_CMDS which will override the

bmon: make ncurses dependency optional

bmon can be built without ncurses support (needs a small patch though),
so don't enforce it in kconfig.

bmon: link dynamically unless explicitly requested otherwise

Commit 009d8fceab4d (add --{enable,disable}-{shared,static} automatically)
caused us to pass --enable-static in the normal (non-static) case as well,
which bmon interpretes as a request to link the bmon program statically,
bloating the image.

Fix it by passing an extra --disable-static to bmon configure to nullify
this.

package/autotools: add --{enable,disable}-{shared,static} automatically

For target packages, depending on BR2_PREFER_STATIC_LIB, add the
correct combination of --{enable,disable}-{shared,static} flags to
./configure calls.

  * When BR2_PREFER_STATIC_LIB is enabled, we pass --enable-static
  --disable-shared.

  * When BR2_PREFER_STATIC_LIB is disabled, we pass --enable-static
  --enable-shared. We enable static libraries since they can still be
  useful to statically link applications against some libraries
  (sometimes it is useful for size reasons). Static libraries are
  anyway only installed in the STAGING_DIR, so it doesn't increase in
  any way the size of the TARGET_DIR.

For host packages, always pass --enable-shared and --disable-static.

busybox: adjust configuration for non-MMU targets

The swaponoff applet doesn't build (and doesn't make sense) on non-MMU
platforms.

The ash shell cannot build on non-MMU platforms (because it uses
fork()), so select the hush shell instead.

toolchain: introduce BR2_TOOLCHAIN_HAS_SHADOW_PASSWORDS

Unfortunately, the official Blackfin toolchains are built without the
shadow password support, so our default Busybox configuration fails to
build.

Therefore, we introduce a new hidden knob
BR2_TOOLCHAIN_HAS_SHADOW_PASSWORDS, which is set to yes for Buildroot
internal toolchain, for toolchains generated by the Crosstool-NG
backend, for Glibc external toolchains and for Uclibc custom external
toolchains. It is left unset by the Blackfin toolchain profile.
