[ELDK] [PATCH v2 2/2] META-ELDK: u-boot: unbreak target U-Boot build

[Gerhard Sittig]

add a build dependency on openssl and openssl-native, since boot loaders
may need it depending on their configuration, and image conversion tools
unconditionally need it (and don't use external u-boot-*-native
packages)

pass additional EXTRA_OEMAKE parameters, to unbreak the build for both
image conversion tools that are run at compile time on the host, as well
as for target objects that get built from sources that were created from
binary resources at compile time (logo bitmaps)
