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.

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.
