[Buildroot] BSP patch vs 20070208 (updated according to suggestions)

[Ulf Samuelsson <ulf@atmel.com>]

Author:    Ulf Samuelsson

Log:
    Here is my suggestion for supporting different BSP's
    in the same buildroot structure
    Updated according to suggestions.
    BR2_BOARDNAME cannot be empty,since it is used to define directory
names.
    I don't think it should be defined by the targtets, since you may
want to build
    several different boards, using the same target

    Add BINARIES_DIR directory,
    where resulting binaries can be stored
    Typically this directory contains a subdirectory for each BSP.

    Add TARGET_BUILD_DIR directory, where BSP for different
    boards can be built without destroying results of previous builds.
    Typically each BSP would build in a subdirectory of TARGET_BUILD_DIR
