Some barebox targets need to build host tools (for example rockchip64
uses scripts/rkimage) that require some host libraries, such as
host-openssl or host-libusb. These are detected by the Barebox build
system using pkg-config.
In order to allow supporting such Barebox configurations, we add two
new options: BR2_TARGET_BAREBOX_NEEDS_OPENSSL and
BR2_TARGET_BAREBOX_NEEDS_LIBUSB that respectively allow to ensure that
host-openssl and/or host-libusb are built before Barebox.
Additionally, $(1)_MAKE_ENV is adjusted to ensure that when pkg-config
is run by the Barebox build system, it finds host libraries. This is
similar to what is done in U-Boot.
This allows to fix the following build failure:
HOSTCC scripts/rkimage
Package openssl was not found in the pkg-config search path.
Perhaps you should add the directory containing `openssl.pc'
to the PKG_CONFIG_PATH environment variable
Package 'openssl', required by 'virtual:world', not found

Adds support to build barebox with an auxiliary config.
This is useful for building an SPL (Secondary Program Loader) in
addition to the traditional TPL (Tertiary Program Loader). The
Beaglebone Black for example has two barebox configurations:
- am335x_defconfig builds the full barebox bootloader with device
tree
- am335x_mlo_defconfig builds the smaller MLO bootloader that loads
the full barebox bootloader from the eMMC or SD card.
Tested with the following defconfig:

BR2_cortex_a8=y
BR2_ARM_EABIHF=y

No functional changes. In preparation for the auxiliary barebox build,
boot/barebox is split into two parts:
1. boot/barebox:
- The source and patch specification which are to be shared between the
barebox and barebox-aux packages.
- The barebox-package function and build logic.
2. boot/barebox/barebox:
- The package configuration, fragments, barebox env, etc.
- The actual barebox package make instantiation.

Support optional selection of the built image filename in a
multi-image barebox build. This makes it possible to specify which
image to pick in a multi-image barebox config such as the
am335x_defconfig.

[Thomas:
- remove default "", since this is the default for string options
- rename the prompt from "Barebox image filename" to "Image filename"
- slightly improve the Config.in help text.]
