The bootloader being very specific to the hardware, being able to
build U-Boot from an arbitrary tarball available on the web might be
needed.
Therefore, for U-Boot, we provide two methods :
* Get a given stable version from U-Boot official FTP server
* Get an arbitrary tarball
This should hopefully satisfy most needs, without complicating too
much the U-Boot build procedure on Buildroot side.

Remove all the bootsource selection mechanism and the horribly
complicated BR2_TARGET_UBOOT_DEFAULT_ENV thing, which wanted to be
generic, but was in fact very AT91-specific.
Just keep things simple: we build U-Boot with the board configuration
file specified in BR2_TARGET_UBOOT_BOARDNAME.

To build mkimage for the host (which is needed to build an uImage of
the kernel), it is not necessary to configure U-Boot, and therefore to
have a particular board selected.
Therefore, this commit:
* Adds a verification at U-Boot configure step that a U-Boot board
name has been defined
* Sets a default U-Boot version if none has been specified, so that
even when U-Boot isn't selected but we want to build mkimage for
the host, a particular U-Boot version is picked.
* Make the host mkimage target depend only on U-Boot being
downloaded/extracted/patched, and the target mkimage/fw_printenv
targets depend on U-Boot being fully configured.

A very complicated infrastructure for just a special case, for an
ancient version of U-Boot. Recent versions of U-Boot are reported to
work just fine on Atmel ARM evaluation boards.

Yaboot does not build, hasn't been updated since a long time, and
isn't very common these days on embedded PowerPC platforms.
