Two separated _recipes_.

 Ideally we ought to ensure U-Boot stops to build the native part when
 doing the target one.

I know but this seems to be the route we ought to pursuit.

Ah ok, to some degree that already exists with the u-boot-mkimage and
u-boot-fw-utils recipes. However the problem is that there is
currently no easy way (at least with mainline U-Boot) to get U-Boot to
use the tools provided by the host/sysroot/PATH instead of building
them.

Are you suggesting that the compile step (of the recipe) should build
the "tools"/native make target first, then execute the make target for
the rest afterwards as two separate steps?

For reference the U-Boot makefile setup handles the dependence on the
tools, and will ensure they are built before needed. So splitting out
the steps is probably not necessary.

Nathan

[OE-core] [PATCH v2] u-boot.inc: Add host compiler flags and openssl-native dependency

[Nathan Rossi]

U-Boot will compile its own tools during the build, with specific
configurations (aka when CONFIG_FIT_SIGNATURE is enabled) the host tools
require openssl. This patch adds 'openssl' as a PACKAGECONFIG that
enables the use of openssl-native as a dependency and also adds the
HOSTCC flags that U-Boot uses when compiling the host tools.

Changes in v2:
* Changed from using an unconditional DEPEND +=, to using PACKAGECONFIG with
  the "openssl" config and defaulting PACKAGECONFIG to enable the "openssl"
  config.
* Reworded the commit message and comments.
